good dim sum after 3?
Ocean Bo Dim Sum Cafe in El Monte serves dim sum after 3pm. It's not the best dim sum, but it's decent... and cheap. Most dim sum dishes only cost $1.70.

None of the seafood palaces serve dim sum at that hour, but you can order in certain (less savoury-looking but still quite tasty) places... I know you can get various dim sum at Green Village, including their wonderful XLB, or at Shau May on Garfield/Garvey (or the Valley Blvd. branch)... and I believe Dim Sum Express, on Garfield about 2 blocks south of the 10, is open until 5, but it's strictly takeout -- there's not a single solitary table.
Unfortunately, there are no restaurants that serve dim sum after 1 p.m. or 2 p.m. (depending on the restaurant) which depresses me because I am a late riser sometimes, and I also work on Saturday and Sunday mornings, which makes it even more difficult for me to grab dim sum. What I can suggest is you to start a restaurant that serves ONLY dim sum 24/7. :) I myself was going to start it, but I lack the initiative, money, and the motivation to actually start it. So if you do create a chain that serves dim sum 24/7, know that you will have at least one customer visiting often. :-D
