I'm presuming it's the Crowne Plaza downtown, right? I haven't been to a function there yet, but most of the hotels in the downtown core are pretty standard when it comes to food. It's in a great location, close to the club district. My boyfriend actually lives a few blocks away from there!
Check out
www.toronto.com and go to Bars & Nightlife. Anything in the entertainment district is nearby.
There's a great strip of pubs/bars along the Esplanade. My fav. is the Bier Market. It's got a ton of beers on tap and has great Belgian frites. They're thin and kind of crispy and come with different mayo flavours to dip them in.
Standard hot spot include My Apartment, Joker, Joe...I like Schmooze, Tonic's a definite club-club w/the girls in short skirts and boots/guys in slicked spiky hair and black shirts. The newest spot is Seven.
If you want to head up into Little Italy (about 15 minutes away) there's a whole strip along College St. past Bathurst. Lava Lounge, Sou Daz, Ciao Edie are great spots.
Just to name a few
