In Queen's Quay Terminal, steps from where you are staying, is a restaurant on the second floor called Pearl Harbourfront. Ask for a window seat. The food style is very clean, rather nicely articulated for dim sum. Aside from Lai Wah Heen, it is the only good dim sum restaurant downtown, in my opinion. (More traditional, less avant garde than Lai Wah Heen.) If you're curious, there is a northern dim sum place on Dundas east of Spadina, called Wei Shiang Tsuen (Asian Legend). Quite different and rather yummy. Beef & green onion pancake rolls, pot stickers, glutinous rice packed around shredded pork and oil stick.
