This place is supposedly to be famous for their chocolate cake.
They ordered the cake and were told all were sold out. The service staff recommended other items on the menu. Finally, they settled for another two desserts.
The items came and the food tasted awful. So were the drinks.
20 minutes later, the service staff came and informed them that the cake is now available. At that point, two persons asked spontaneously, "Is it complimentary?" The staff was stunned and walked away without answering.
