Review of Johnny Utah's

Not certified GF, but it does have chili, nachos, and salmon on the menu, which worked fine for us. For Rockefeller Center, this is a low-priced restaurant with lots of room - can reserve with Open Table. There is a flight of stairs to go down to restaurant, but the hotel next door has an elevator if you ask. Good bar area with 2 high tables & 3 tvs, 2-3 separate rooms for dining, plus they have a mechanical bull. Family-friendly.
