Yes, Sam Woo in Irvine, CA is open on Thanksgiving.

Varies, but I wouldn't worry about the price.

Yes.

Open as usual

Always

My favorite dish: Shuicao noodle soup. The egg noodle is the best here (on the BBQ small one, not the seafood one)

Steamed fresh shrimp. Lobster or crab Hong Kong style. Fish fillet with tofu.

Yes
