In the summer, I found the simple outdoor decor - white plastic chairs and tables - a pleasant, quiet place to relax with a cold one. (Cold ones used to be 5 rmb, but I think they raised the price to 10 rmb.).
I don't know much about the Russians dancing inside (seem to arrive on about 9 or 10 pm), but outside was peaceful and sometimes a different language at each table. (Inside can get a bit loud.).
Also early in the evening inside can be convenient place to meet, talk, etc. before the music gets too loud.
Located on street connecting Zhongshan Square and World Trade Building (Dalian's tallest). Opens 5 or 6 pm?
