Great Eastern - A venerable (opened in 1986) two-floor Cantonese seafood palace located on Jackson street in Chinatown and open until 1 a.m. In the classic Hong Kong manner, tanks along the back wall are filled with live seafood. Check out the price per pound of your favorite specie, point to your swimming meal of choice and be eating it minutes later. That is fresh seafood. Although the critics and the city's concierge contingent wax poetic about Great Eastern, my experiences here have been mostly unimpressive (including one mild case of food poisoning). No recommendation.
Harbor Village - Somewhat hidden off the beaten path on the second floor of 4 Embarcadero Center, this is the definitely upscale California branch of a highly regarded Hong Kong restaurant chain. The room is gorgeously decorated and elegant with large windows looking out over the Embarcadero and the bay. Although prices are high and service complaints are common, the food here is excellent. This is good choice for showing visiting out-of-towners upscale dim sum. The dinner menu has an extensive selection of classic Cantonese dishes. Recommended.
