I’m hosting a cocktail party for about 100 people and want to off-set some of the catering charges. I was thinking of picking up some frozen appetizers at Costco and having the wait-staff heat and serve these. Any recommendations to please a crowd?

Hey gang,
We’re looking for a place to celebrate a friend's 30th birthday in downtown Toronto. Can you suggest a restaurant that meets the following conditions...?:
* Able to seat 15-20 on a Saturday night
* Near nightlife (Queen W, King W, College St, etc.)
* Reasonably priced (not too high end)
* Not a chain (i.e., not Alice Fazooli’s, etc.)
* Able to offer a la carte ordering (i.e., no fixed menus)
Thanks for any and all suggestions!
