Great American Food Eatery in the heart of Downtown.
The venerable Caz's Bar across the street in the heart of Tulsa's Brady Arts District opened this pub / restaurant a couple of years ago and we can't stop going. Try it for lunch, come at dinner, show up on the weekends...any time there is never a wait and the service is fast, friendly, and they always serve up great American food.
I highly recommend the "pucker chips" for an appetizer and try the Shrimp Po-Boy for lunch and the Chicken fried steak for dinner. Be sure that whatever you do, strap on the stretchy pants first because their portions are HUGE.
