Wait staff was very knowledgeable about celiac disease. Many entrees are naturally gf, while other items they can make substitutions to make gf. Wait staff made sure to tell the kitchen I was celiac. I have silent celiac so it's hard to know if I've been glutened, but the staff seemed to know enough about celiac for me to trust them. Would have liked more gf dessert options (only had one option plus sorbet), and for pasta dishes to have better pasta substitution options (they only have rice noodles as the gf option) but overall very good experience. Hands down best food in Waterloo celiac or not.
