We have an A&W that’s fairly close and we also have a drive-in called A & Dubs. It’s a family-owned restaurant. They make their own root beer that rivals A&W. Great burgers too.
In Elmhurst IL, at the north end of downtown at York Rd. & North Ave. is this place. Their website says
So, nine X’s?
It’s nice, but the town not so much. Well not the town itself, the people from the town. It’s a welfare town with a large drug addict population. I worked there in the 80’s and it was going straight down hill even then. I do like the A&W though, I feel like I am living dangerously when I go there. 
That and the foods pretty good.
There’s a pizzeria in Greensboro (I used to go to one in Winston-Salem when I lived there and it was still open) that is unduly proud of its house-made root beer, but I never knew them to serve it in a frosty glass mug, just a run-of-the-mill restaurant-supply-house stackable plastic tumbler.
They did make good pizza, though. Twenty-odd years ago.
There are a couple of old school drive in root beer stands left in town. There’s also a Sonic, and while I suppose one could order a root beer there using the car hop service, it somehow seems spiritually different.
Just had dinner at an A&W drive in a few weeks ago and the root beer came in a large glass mug.
The New Mexico Farm & Ranch Heritage Museum occasionally hosts events at which food is served. There is a guy who sells sarsparilla, root beer, and other “old-fashioned” beverages out of a cart designed to look like a cowboy chuck wagon.
I’m starting to see that along with the craft beer movement there has also been a craft soda pop parallel. Independence Missouri has a place called Polly’s Soda Company.
I SOOO want to try that place!
Looking at the menu, ours sounds much better. Miracle Whip? Ugh. 
A bit over an hour away, in Middlebury, VT, is an actual A&W drive-in with car hops on skates. Takes me waaaay back.
There used to be a burger joint across from my high school that served ginger beer in a frosty mug. We went there all the time. This was over 55 years ago, and the place has changed owners several times. I don’t think they still serve ginger beer.
St Louis here…Fitz’s Root Beer ROCKS.
I worked in a place a long time ago that was previously an A&W. Still had tanks and a LOT of glassware in the basement. I have a fair collection including a few tiny sampler mugs.
Besides the Triple XXX (also known as the "Tri Chi), Tippecanoe County boasts two of the 14 remaining Dog N Suds locations. In addition, the Lafayette Brewing Company crafts a root beer to complement its alcoholic offerings.
You won’t get any resistance from me. I’m an IU grad and Triple XXX is in Purdue territory (huge state rivalry). I’ve eaten there once and thought it was ok but nothing special, but I can understand their nostalgia.
On the other hand… don’t be dissin’ the tangy zip of Miracle Whip.
The last one anywhere near here closed 10 or 12 years ago.
There is a quaint little root beer stand over in Waukesha. My wife thinks there was a Dog n Suds in the same area back in the 70’s. I wouldn’t know, I didn’t grow up around there.
But speaking of Dog n Suds, there are a couple of them across the border in the northern flatlands. Their root beer is pretty good.
XXX Root Beer in Issaquah, WA. I haven’t been in years (it’s not an area I go to often, and when I do I’m on my way back from a hike, and I usually am more in the mood for root beer without the root). http://triplexrootbeer.com/
