Gold Mountain Restaurant in SF Chinatown is a pretty famous place for dim sum, but I honestly don't think it's that great. It's great in terms of SF food, but it still doesn't beat So-Cal dim sum. Yum. The dinner menu is a bit better. The seafood is very fresh, but like most chinese restaurants, the food is very greasy packed with MSG. It's a very big place, so you don't feel too crowded.
