capital seafood on la cienega just north of wilshire, service hours are like 11-3 or so weekdays, 10 am weekends. it’s good. no carts but pretty thorough menu of dim sum. It’s a branch of a spot in SGV.
Here’s a few photos of some recent stuff…they have a lot more - it’s not shown on restaurant website for some reason (the fold out menu from Arcadia seems identical)
