Rude guy. Was waiting for my gf outside in of their chairs. It was going to be our first time eating here and the guy comes out and kicks me out. I ask "am I not allowed to wait here" and he says "it's only for customer" in a extremely rude manner. I got up and left. Told my gf to meet me elsewhere to eat lunch. Their attitude is probably the reason this place is always empty. Kind of sad that we actually considered eating here and this is how I was greeted.
