Review of Burger 21

We've been ordering from here for about 4 years, and Burger21 has been very consistent in food quality and lack of adverse effects re: Celiac. We've tried a few of the different burgers available in gluten-free (GF), but mostly stick with the Bacon Cheesy on GF bun (good!) and GF fries. Whenever special comments are available on item(s) or the whole order when ordering online, I always note that there's a gluten "allergy" and to please try to avoid cross-contamination when preparing. Recommended. Edit: We do takeout/delivery 99% of the time. We've only dined in once.
