Though I only had a meeting here last month, I can verify that it's authentic yet slightly modern-decorated, which is a very good thing in this part of Chinatown in TO. meaning that compared to the other older-looking establishments that probably need any type of renos, Si chuan is clean and i'll try it next time i'm in town.
but judging from the food served, can vouch for generous servings & smelled good. Even the locals will go there, know what i mean? ;)
And the washrooms are good & clean too, b/c they don't have the typical mop in there lol.
