They do not have a GF menu, but each time I've been here, a manager has come to my table to let me know what my options were. Since I am dairy free as well, I really appreciated the extra effort. Staff is very friendly and knowledgeable. I have gotten a burger on a lettuce wrap with veggies as a side, and grilled chicken with white rice and veggies. I've never gotten sick.
Not a lot of options, but the Chicken or Beef 49'er is wonderful. They also have potatoes and steaks. I've never gotten sick eating here.
