Went to Shanghai Dim Sum for dinner tonight at the suggestion of a friend, and here was our experience:
Even though the restaurant was empty other than a table of 2 (it was 6:30pm), the staff was hesitant to give our party of 4 a larger table that sat 6. We assured them it was because we were planning to order so many dishes that the table for 4 would be tight and eventually they relented since there was no one else in the restaurant.
The 4 staff members (one of whom appeared to be the owner or manager) hovered over us and kept speaking to us in Mandarin even after we apologized that we don't speak the language.
Tried to get their attention a few times to refill our tea, but they were chatting to each other and did not assist, even as they stared at us.
One of the waitresses was picking her nose, which prompted my husband to comment that if they behave that way in the dining room, goodness knows what goes on behind closed doors in the kitchen.
The food was very good, but service severely lacking. Our party was torn as to whether we would make a return trip - the food would make it worthwhile, but it would have to be take-out.
