The head chef of R&G left a while back and is now at Hong Kong Flower in Millbrae. R&G's food is still good but imo a few of their more famous dishes ie. salt and pepper crab has dropped a bit in taste.
Koi Palace is good and has a ton of variety, but as mentioned above, make a reservation or be prepared for a 20+ minute wait. If you're located in Palo Alto, a closer option is ABC in Foster City. In addition to dim sum, try their roast duck and egg yolk pumpkin crab.
