First time at this location (have also visited in Denver). Regular menu is marked for items that either are or can be prepared GF. I didn't ask about the shared fryer, but ordered chips & salsa. Only ate a few just in case -- so far, so good. I'm not celiac, but highly sensitive so usually I can tell within 30 minutes if there's been cross-contamination. Street tacos are delicious. The atmosphere is fun (bowling, old school video games, and more) and they make great drinks. Would definitely recommend.
