I'm afraid I can't add much in the way of food specifics, but I did have dim sum at Shui Wah last month, and even though our visit began with a line jammed at the front entrance, it moved quickly. We had excellent service from initial set-ups to ordering to busing throughout the meal. Everything seemed fresh and good. And the final tally was astonishingly low. I look forward to returning.
Haven't been to Phoenix in over a year. My memory of the last visit is that it was unexceptional. Food was decent. Service was OK. Sometimes the carts were hard to come by or there was longish gaps between visits to our table. But nothing to raise the blood-pressure. Still, I actively look forward to my next Shui Wah visit.
