Toronto - Business Dinners

I'm looking for chowhounds' recommendations for interesting restaurants for business dinners in Toronto. I usually have 8-10 (gastronically sophisticated) people in the party. Price is not really a factor but we prefer to be reasonably close to the Yorkville area. In the past I've tried Prego, Bistrot 990, Jump, Verona. Does anyone have any views about Scaramouche or North 44? Anything else new? Has the restaurant in the Park Hyatt opened yet? If so, is it any good? Would Thai Magic or Chiado be okay for business dinners? I've read the chowhound archive on Toronto, but most suggestions seem like the places I'll go on my nights off, not for business dinners. Also, any suggestions for restaurants with nice private rooms (like Jump and Verona)?
