Love dining here, we really need more spots like this in downtown Toronto. I find Chinese food is typically not served in nicer establishments with good service. I always take my friends who aren't necessarily familiar with Chinese cuisine and it's always a hit.
I ALWAYS get the soup dumplings here, I'm glad I moved offices because my wallet would hurt everytime I come here for lunch and order them. They are addicting and you will crave them. Tip: put a drop of chilli oil on the soup dumpling and eat them whole.
I've tried quite a few other items and they're all very good. Even a dish like "braised eggplant" (which might not sound appetizing at first, but it's amazing). The lunch menu is very filling, you won't need to order anything else on top of it. For dinner, the plates are usually shareables for the table.
Only thing I dislike about this place is the prices.... I used to live up north and would frequent North York/Markham/Richmond Hill for Chinese cuisine of the same quality and they weren't this expensive. In Chinatown you can probably find the same dish at half the price as well, however I personally haven't found a spot that I like more than Lee Chen in Chinatown.
