I'm reviewing this based on the dim sum that Sun Penang has to offer. We went on a Saturday afternoon for dim sum. We quickly were offered the first of two carts, from which we selected several items. I would say that the items in the carts were a bit more towards room temperature than the items ordered off of the menu. Everything was pretty good (although I would not recommend the spring rolls). The two items that stuck out were the pork dumplings (that had a ton of filling) and the malaysian cake (which was like the best angel food cake I've ever had).
Overall I would definitely recommend Sun Penang for dim sum.
