The Golden Inn is my favourite restaurant Cantonese-style Chinese restaurant in the city. There's a reason why this place has been around for so long and it's because of the great food and fast service. These guys are very efficient and never mess up your food order. As Al B. and Spencer B. mentioned, you can order things that aren't on your menu. They'll accommodate everyone, including my mother's "little salt, little oil" requests.
They also cater to the late night after-bar crowd. Don't go to Singapore Sam's, guys. Make the trek to Golden Inn because it's less greasy and they have an amazing seafood tank.
