Rol san is my staple dim sum place, but you need to order the right things from the menu as I think they've perfect some dishes and neglected others. They changed the formula of the clamari as it is now more sweet than savoury, it's improved but not worth ordering. What is best is the spareribs (cant get this good anywhere else), tripe with ginger (the best), short ribs with black pepper sauce. I also like the pumpkin cashew dessert items.
