Lai Wah Heen used to be excellent, but has recently changed hands. I haven't been there since, so I don't know if the quality has been affected.

There are two good places for dim sum close to your hotel: Dynasty, which is on Yorkville (and next door to my apartment building), and Crown Princess, which is a couple of blocks south on Bay St.

I'm a regular at C'est What, and the beer selection is very good - almost entirely Ontario micros. Plenty of hoppy beers available, and many of the staff are quite knowledgable. If you have mobility issues though, you should note though that it's in a basement, and you'll have to walk down stairs to get to it.
