I repeatedly called for reservations but was not picked up. finally came directly around 10 in the morning, but was refused with the reason that it was full. even though I see there are no customers. Finally, Ms. decided to serve me at 11.30.
apparently only about 30 minutes I was called again. I see in the room there is 1 person being served, but whether it's a customer or fellow staff too. actually the staff are quite friendly, but yeah the initial reception makes it less comfortable.
