I absolutely love Blue! I stop here anytime I'm in the area. They are very careful and have a gluten sensitive menu. A dedicated sushi maker uses a dedicated station to make the GF sushi and I've never gotten sick. It's not cheap but you get what you pay for with sushi. Every server I've had was familiar with the gluten free options and was very helpful. They no longer print the GF menu but it's online and not hard to find.
