The kitchen is 100% gluten free. There are a few things that have gluten in the front of the house such as one of the ice cream flavors and beer, but cross-contamination would be unlikely. I read here that some of the toppings have gluten but when we visited there were none that had gluten. My husband ordered a savory waffle - he had the pastrami sandwich. It was fantastic! My son & I both ordered from the sweet waffle menu and had ours topped with fresh strawberries and coconut (non-dairy) whipped cream. Oh my gosh, we were in heaven! We also played games while we were there. Each person who plays games pays $5. You can stay as long as you like and play as many games as you want. After, walk a couple of blocks to enter Golden Gate park to walk off those waffles! We'll be back!
