Went inside and wait at the sign which said wait to be seated, 3 staffs stand 5 meters away from me, talking to each other, one of them I think is the waitress, another one is bar tender, the man next to him should be the manager. After I look at them for one minute, the waitress come to me. I asked her whether I can seat outside. She said yes and asked whether I just need a cup of coffee. I said yes. Then I waited at outside for 15 minutes. Still no one tried to server me. Then a waiter went outside with the manager. I told the waiter what I want. And this is the end. Very disappointed, I won t come to this restaurant unless I do not have a choice in the future.
