Knowledgeable waitstaff, several tempting options, and much of the gratis appetizers were GF. I didn't care for my mackerel dish, and it could take a while to flag down my waiter to confirm new arrivals, but overall a good experience.
Excellent Korean food!!! Stay away from dishes containing soy sauce and marinades and you should be fine. Personally I love the Kimchi Jjigae, seafood BBQ (order not marinated!), steamed eggs, etc. I am incredibly sensitive to gluten and have never gotten sick here.
