140 San Gabriel Square
I don't think this qualifies as great because there are better places for dim sum, but maybe New Capital?
There are a couple decent Taiwanese joints too like Nice Time Deli and Ay Chung. Aside from these and Sam Woo, I haven't had any too many mind blowing eating experiences at this plaza.
There used to be an Islamic Chinese restaurant that wasn't bad as well, but I think it closed down and/or moved to another location.
