First, lets set the parameters for this thread. To count as a chain a restaurant must have a minimum of 3 locations. And since I mostly want to hear about chains that aren’t really well known outside their home regions, for the upper limit let’s say they should be mostly located within one state, although I’ll allow a small number of locations across state lines.
I’ll start, for the NorCal region, mainly the Sacramento area.
Beach Hut Deli is the chain that inspired this thread when I mentioned them in another thread a few weeks back. I didn’t actually realized they started in the Sacramento area (Their first location was in Granite Bay, specifically). They now have 45 locations if I counted correctly, with the highest concentration around Sacramento but also many elsewhere in California, plus two in Oregon and one in Nevada. They’re known for thick, meaty sandwiches that make generous use of cream cheese and avocado, and they’re very tasty. They are my go-to sandwich place.
Jimboy’s Tacos is also a Sacramento based chain, with over 40 locations according to Wikipedia (I didn’t bother counting the exact number). Again, the majority of them are around the Sacramento region, plus a couple in Reno, and apparently one oddball location in Fort Worth, TX. I actually avoided them for a long time after I moved to the area, because they just looked like Taco Bell style fast food tacos, but I finally decided to try them recently. Yeah, they are crunchy tacos filled with seasoned ground beef, cheese and lettuce, but they just the outside of the shell with parmesan cheese, so you get this burst of umami in every bite. So their signature taco is actually pretty tasty. Everything else does seem to be pretty much standard Tex-Mex fast food, though. But I would say a bit higher quality than Taco Bell.
Squeeze Burger (Formerly Squeeze Inn), was featured on Diners, Drive-Ins, and Dives back when they were still in their original Sacramento location, which only seated about 10 people (hence the name). Now they have four locations listed on their web site, but I don’t think that’s up to date, because there’s a Roseville location that’s not listed there. Plus they have a few food trucks. They’re known for the “cheese skirt”, which is probably better explained by just directing you to the pictures on their web site.
Chando’s Tacos, is a repetitively new establishment, founded in Sacramento in 2010. Now they have 8 locations around Sacramento, plus some food trucks, and apparently now they have a franchise in Atlanta. Many, including me, consider them to be the best burritos in Sacramento.
