I was fortunate enough to visit on a weekday morning instead of the weekend, to avoid the crowds. We ordered a congee, a beef roll and a deep fried dough stick. I think all up it was under $20. The food wasn't outstanding, but it was good value for money.
Service was so so, considering that we order and pay at the counter and take the food on a tray to an available table ourselves. All the chopsticks/spoons/tissue etc are already on the table.
Half Time Tea Bar serves lunch and dinner as well, but I am reluctant to try......... there are many more options for lunch/dinner in Sunnybank. Their lunch and dinner menu looked most ordinary.
