Dynasty is my favourite dimsum spot in the city for the simple reason that it is not in Chinatown. Dynasty is fortunately located at the (ritzy) corner of Bay and Bloor. Thus, the place is spotless and the washrooms are relatively clean. Now, I'm a big fan of inhaling a bowl of noodle soup in Chinatown (where I avoid the restaurant washrooms at all costs). However, the thought of ingesting 4-day old dumplings after being re-steamed does not appeal.
Back to Dynasty and its yummy dimsum. The dishes are just plain tasty, fresh and familiar. For the adventurous, I highly recommend a dimsum delicacy called "Octopus Fingers" -- keep an open mind and let the tentacles seduce you. The one downside of Dynasty is they do not push the dimsum carts around, so you have to order off a menu check-list.
Get there early on weekends (especially during winter) as the wait could get stupid. They do take reservations. Parking in the basement garage during weekends is free. I only go here for brunches because it's just too empty during dinner hours. I took a group here for dinner a year ago on a Wed evening and we were the only ones there.
