Good news: some of the best dim sum our group has ever eaten.
Bad news: with their quirky unreliable reservation process you could end up waiting an hour (or more) to get seated.
The decor is Old English Country Manor, with each room (main, upstairs) packed in with dinner tables.
Arrive early, be patient. Final bill was much higher than most dim sum places, but we didn't begrudge it because of the high quality of the food and service.
You can get there reasonably easily by transit; there are a limited number of parking spots.
