Culver's Gluten Free Celiac. Please let me know if there is anything else i can help you with. Culvers has a pamphlet on allergy information in the restaurant and it lists gluten in it.
Pure wheat grass and barley grass are. These are all the gluten free options we could find at culver’s. Although you can't get fries or curds, there's a pretty decent range of options that includes some of their most popular menu items.
Asian box has 10 locations in california and one of them is in san francisco.
Gluten free bun comes wrapped separate. However, normal kitchen operations involve shared cooking and preparation areas and we cannot guarantee any menu item will be free of allergens. If you order a gluten free bun, you'll likely receive a deconstructed burger with your desired toppings with the bun on. I was hesitant to eat there because i was scared that i would get some sort of cross contamination, but i was actually surprised at how well they understood and made sure to take every precaution necessary.
