Okay, I’m an amateur, but I want to eat at all of your restaurants.

Also interested in the regional take. A lot of this, like meatloaf and mac & cheese, I think are pretty universal. Here’s a few that I think would be pretty common comfort foods in my area.

Chowder, clam or fish (option, oyster stew)

Meatballs, on spaghetti or in a baked sub with provolone

Franks, baked beans and brown bread

Boiled dinner (corned beef, cabbage and all the trimmings)
OR Pot roast with thick brown gravy, mashed potato and boiled veggies.

Any kind of baked pasta (baked ziti, lasagna, manicotti, even American chop suey)
