I'm going to repost my review from another site. Recommend that Chowhounders check it out and add your own opinions:
We visited for dim sum on Sunday morning, the place was about 2/3 full. The carts were nonstop, delectable, and laden with all of the normal dim sum offerings, including plenty of Cantonese broccoli with garlic and cucumber salads.
We had fried squid; clams with bean sauce; cucumber salad; and char sui beef noodles (fat noodles); and chicken feet. Everything was very good. I like that the food was lightly spiced so that you can add as much soy and hot chili oil as you like to meet your personal taste.
The clams were great: succulent, slightly briny, and cooked perfectly. The squid was the same, with plenty of nice and delicate purpilish tentacled pieces on the plate. All of the food was as it should be and (thankfully) no MSG afterburn as we've experienced with a couple other places in NoVA in recent months.
Service was impeccable, we were asked by the waitresses at least 5 times over 45 minutes if everything was OK, and there were lots of carts coming by throughout the meal.
It's great to have a new Cantonese and Sunday dim sum offering in the Falls Church area . We've been to Fortune twice in recent weeks, Hokkaido a couple times, and Mark's DH in not more than once in the last year+.
We'll definitely be going back to HK Pearl.
