This is THE BEST Mongolian BBQ around. Owner and staff and very friendly. Line to start is usually long and slow as expected, so don't expect to be in a hurry.
My wife is gluten free and brings her own gluten free sauce. If the owner is there, you can let him know and he will mix them up and get you just the right flavor or you can do it yourself. Just let the staff know so they can scrub down the grill for you first and cook your separately.
