About 20 people will have dinner in Dalian. Please recommend some places.

I'll just mention a few small places we've been to: a big table for 20 people.

Tangshan street: mainly Sichuan style,

Convention and Exhibition Center: Chuanwangfu

It's all big rooms.

We have been to Xin Peninsula, but they are all home-cooked dishes, and the taste is average. We prefer Sichuan food.

I recommend you to go to the second floor of Roosevelt again. It seems that Baweide barbecue buffet (No.2 Canxi barbecue in Heping Square) is delicious.
