Worst service

We arrived just before 8:30, and told we could not be seated, only take away as they close at 9pm. We placed our order, just Tom yum soup and another meal. a group of 8 people arrived after us and placed a huge order. At 9:05, the cashier says that she does not have the mushrooms for the Tom yum soup, I said it's fine, 3 min later they call up the order for the huge group AFTER us. When we asked if they started our soup... They said they did not... And were about to. The owners of this establishment should seriously look into how their staff are running the shop. Unacceptable service.
