Thank you for sharing. We will not take chance to "suffer". Just to let all LYK know the event we have too.
We went to "rincx" on 12th in Vancouver, having the similar problem.
Fried shrimp waton served without sweet and sour sauce. Server came back with other dim sum for next table and Captain came back with answer that chef is making freash sauce. Sauce came 5 minutes after but the temperature is warm only not hot.
