Like most restauranta in LA, Four Sea is in a nondescript strip mall. I've never been to Joy Sauna, but Malan Noodles next door is pretty good if you like hand pulled noodles made on site.
Look, you can't beat the prices. I can usually eat for $5, or stuff myself completely silly for a few dollars more.The danger is that I always want to take home $20 worth of stuff too.
During our most recent visit, we settled for a gua bao (steamed bun filled with braised pork belly and pickled mustard greens), sao bing (flakey pastry dough filled with pork loin slices), you tiao (deep fried bread), and savory soy milk with green onions and you tiao in it. There are two round pastries on that plate to the left as well, one filled with sugar filling and one with turnip.
