We tried Sea Garden for lunch on a weekday. It was busy, but not crowded, and they serve Dim Sum. It's clear from their name and the glass fishtanks that seafood is their specialty. The Dim Sum is definitly high quality, but you definitely pay for it.
We tried several dishes, from shrimp balls to pork dumplings to fried bean curd wraps. Seafood is definitely their strong point, although all the dishes were good. We also tried some congee soup, which wasn't that great. The biggest downside is the bill, which turned out to be about $15 per person for an average lunch. That's pretty pricy. Their dinner menu was also pretty pricy. You get good food here, but it'll cost you.Bottom Line: Good food, but you can find more for your money elsewhere.
