I can vouch for Habit in California, Blake’s in New Mexico and Braum’s in OK.
I can vouch for Taylor’s Maid Rite’s in Iowa, you truly feel like you are in a 1950’s diner, because you are!
There is usually a nice turnstill on the end of the counter with lots of pie options.
As an aside, if you’re ever in Greenville, OH, they have an original Maid Rite and it is excellent.
Learned that the Taylor’s son was in WWII and he told his battle buddy, “if we get out of this alive, I will set you up with one of our restaurants.”
And he did.
Caution: If you are looking for a Maid Rite, make sure its an OLD and ORIGINAL location, (Greenville, OH, Grinnell, Newton, Muscatine and Marshalltown, IA). They were bought out recently and the new restaurants microwave the meat and it is NOT the same experience or taste!
