ISO Westside Dim Sum?
Sure. There is or was a place in Westwood Village, just up from Broxton and Kinross, that does dim sum by order (no cart service). It's very expensive and it's not remotely as good as even Empress Pavilion, which is like the bottom end of Chinatown dim sum, which itself pales in comparison to the SGV.
Just drive... you'll be so much happier.
