Nearest pub to my home has been going since 1897. https://athleticarms.com/
Hasn’t changed much.
My family store, Rothman’s Department Store, has been in business for a century. Probably not much longer, though – once my brother retires, he’ll probably sell it.
Around here, there are a few restaurants – The Turf Tavern, Redwood Diner – that have been around since before I got here in 1970. Englebardt’s Wine and Liquorhas been here since 1946, helped by being the closest liquor store to Union College.*
I live right behind a shopping mall and the only stores still there from when I moved in in 1979 is the bank and an optician (who changed location).
Down by my home town, Preston’shas been in business since 1880, selling boating items and souvenirs (originally a ship’s chandlery). Claudio’s Restaurant is even older – 1870 – and is a National Historical Landmark. They’ve opened a couple of other restaurants in the same complex, but the original is still going.
The Greenport Theater is still operating, though it was closed for a time. They turned it into multiple screens: What once was the balcony is now a separate theater and they kept many of the original art deco fixtures.
*They got arrested for selling to a minor recently.
Pubs are acceptable. Not only are they acceptable, but you proved my prediction correct: 
Too many of these are closing.
Becker’s newsstand, in my home town, was there since the 1930s. But newsstands have had their business taken from them in recent years. The store where I bought candy, countless comic books, and many paperbacks closed at the end of last year.
In Boston, the Durgin-Park restaurant, which had been in Quincy Marketplace since 1827, closed last January.
Jacob Wirth’s, founded in 1868, has filed for Chapter 11 bankruptcy and put up for sale
The Locke-Ober restaurant , founded in 1875, closed in 2012.
The only old restaurant left in Boston is the Union Oyster House (1826)
They didn’t move to their present location in Wheaton until the late sixties, though. I thought they moved from H Street in DC after the 1968 riots.
This placejust went out of business after 111 YEARS! (not a typo, read the article linked)
Just down the street from the now closed cigar shop is The Egyptian Theatre
Also, about a mile away is the Boise Train Depot
In Montreal Schwartz’s Deli has been there for 91 years and Moishe’s Steakhouse for 81.
Originally, my gr-gr-great-grandfather’s general store. Upstairs the colonists published the Massachusetts Spy (before 1776, of course).
Shit. You’re the second other Folsomite I know of on the SDMB.
There are two I can think of that have been there “forever” as far as I’m concerned: the Hacienda del Rio restaurant and Snooks Candies, both near Sutter St. Upon checking, the Hacienda opened in 1979 and Snooks in 1963.
The Folsom Hotel says it’s been around since 1885. But I hardly ever went in there, so it’s not quite a local institution to my mind. The Hacienda and Snooks I remember going to from a very early age, and many dozens of times each.
Well,
Antoines could count. Hardly unchanged, but still in the family.
Since 1840. They claim to be the second oldest restaurant in the U.S.
There are a couple of other places in the Quarter that date from the 1800s, but some of them have moved buildings a few times. One of the problems when the buildings are 300 years old and weren’t built to last!
One of the restaurants we frequent is a place called The Tavernette. It’s located in the little village of Medway, Ohio, and has been in continuous operation since 1939. Good food, good drinks, and an excellent atmosphere, I might add.
Since I only moved here in 2005 I honestly had no idea either the Hacienda or Snooks had been around that long. Believe it or not I haven’t actually been to the Hacienda – some coworkers once told me that the food wasn’t all that great and the only reason people go there is for the ambiance. I have taken visitors to Snooks. I’m not sure if the Folsom Hotel would meet my criteria of being mostly unchanged since opening, since it’s now just a bar rather than a functioning hotel (I assume based on the name that it used to be an actual hotel).
Now that I think about it, maybe the Sutter Club sports bar on Sutter Street would count. I’ve never been in there either as it’s a bit too dive-y for my taste*, but it seems like I’ve seen pictures of it in historical photos dating from the 1960s. I’ve always thought of that place as more of a dive than a local institution. Same goes for Folsom Lake Bowl. It does seem like it’s been there a long time, I have no idea how long, but feels more like a dive than an institution. Went bowling there for a workplace team building event once and at the time they were still using 1980s era score keeping computers. I guess that does meet my criteria for not changing. 
Ok, they have upgraded their equipment since then.
How long has Mary’s Gold Miner Cafe been there? A little nondescript restaurant in an older strip mall, I never would have thought of going there if a former coworker hadn’t raved about their breakfasts. When I did try going there for breakfast the place was packed and we had to wait for a table. I guess being that popular may make them a local institution in their own right.
*Ironically, while I really like diners and drive-ins, I’m not a fan of dives.
Although speaking of hotels, there are two hotels up in Grass Valley and Nevada City that have been operating since the Gold Rush era, the Holbrooke in Grass Valley and the National Hotel in Nevada City. Both happen to be closed for renovation/restoration at the moment, but it appears that the owners of both properties intend to reopen them as actual hotels.
Very likely true. I don’t live in Folsom anymore, though I visit my parents there regularly. It’s been probably 15+ years since I’ve been to the Hacienda. I’m sure it’s one of those not-particularly-authentic but serviceable restaurants that you might take a large group of people to with the goal of not really offending anyone. But in any case, they’ve occupied the top floor of that big tan building since forever. And 15-year-old me still thought they were decent.
The better Mexican restaurant was the Sonora Inn. But they got shut down by the health inspector quite a while back.
Not sure, honestly. The first time I’d been there was actually in the last year. Never been a big breakfast person.
Out in the megaburbs here there’s really nothing business-wise around that predates the mid-70s anymore.
E.g., there used to be a long time family farm with a large produce stand on a major highway. Mrs. FtG worked for a bit across the road from it so she knew them some. But about 20 years ago it was sold and now there’s a Walmart complex there.
Even the “old town” near us doesn’t have any old businesses. Because of the poor location off the main roads you just get clueless people spending their savings opening up a shop that isn’t going to last long. The “old timey” restaurant there is only 6 years old. I’m surpised it’s lasted that long.
There had been a really ancient gas station on a corner near us but it was closed when we moved here long ago. Still it was interesting to drive past it. The old bubble top pumps, a rusted out canopy, a tiny cinder block garage, the owner’s house next to it. At some point the pumps went away. Then last year it was replaced by a chain gas/mart thing. A lot of pumps. No bubble tops to be seen.
There’s a gardening shop about a half mile away, that predates our entire subdivision. It’s on a largeish plot of land, and completely surrounded by densely built houses, townhouses and condos. They’ve managed to keep viable, which is fantastic - I live in fear of the day the family decides to cash in on the real estate values.
There was a nearby golf course that finally bit the bullet and sold off to developers. Not a whole lot of green space around here any more.
Almost got married at the Washington Crossing Inn, which was originally built in 1817 and been a restaurant/inn since early 1900’s. My finace at the time (now my wife ;-)) fell in love with the colonial feel.
McGillians Olde Ale House “opened the year Lincoln was elected”.
Not sure if it counts cause it’s been rebuilt a couple times, but City Tavern’s been around since before that pesky dust-up with the Brits
Also may not count, but The Union League is a “private membership club” around since Lincoln’s time as well
Apparently Mark Twain really got around. He was a customer at C.O. Bigelow and the Hotel Holbrooke claims he was a guest there.

[li]Pancake Circus …But you obviously go there for the pancakes – they serve breakfast all day. [/li][/QUOTE]
No, you go there for all the creepy CLOWNS! :eek: And the pancakes are pretty good.
My nomination is 98 years old and from my home town. Far as I know, it’s been in the same place all that time. The Sugar Bowl. It’s Air Conditioned!
Around the corner is a quirky burger place called the Choo-Choo that’s been serving up food by train since 1951. Amazingly, they’ve kept on chugging despite being a couple blocks away from Ray Kroc and his new burger place. At the time, Mr. Kroc thought the Choo-Choo would put him out of business because he didn’t have anywhere for customers to sit down.
The two that come to mind in my neck of the woods are The Cats Roadhouse in Los Gatos–originally built in the late 1800s–and Casa De Fruta, which has been around since at least the 1940s.
