My first time at this location. They have several things that may be GF but there is no mention of allergies on their menu, including no GF buns mentioned.
I just got an OJ/seltzer mix.
Things that might be GF:
Tortilla Chips w/salsa and guacamole
Wings with many sauce options
Chili
Salads
Haddock Filet with Rice Pilaf
Slaw
Veggies and dip (on kids menu)
Could also maybe get a burger with no bun
Note: their tacos are made with flour tortillas
