Chang's Hong Kong Cuisine is one of the best local spots for Dim Sum! All that and Dim Sum :)
I honestly don't know the names of the dishes I really like but it's the baked pork buns, calamari and egg tarts that always has me coming back. I can describe the other dishes that are tasty but I'm trying something different each time I go. The carts come around throughout dining room and it's always nice to see your food or ask for whatever you're looking for. They will also heat up a dish if it's too cold.
Try Chang's for Dim Sum and if you go on a weekend prepare to possibly wait for a table. This experience is all about the food since the service is really only delivering food, clearing plates and filling water or tea. The service I always get is consistent and never had any issues.
