If you want to grab a bite to eat before the game, the Longo's at Maple Leaf Square has a bar/restaurant after the cashiers near the Starbucks and the food is great value. The pizzas there are awesome. Great selection of Ontario craft beer and wine. Overall, a lot more reasonable than Real Sports or any other bar down there.
If you want to splurge, then Real Sports is cool if you've never been but nothing special IMO.
The Scotia Club on Level 200 is a great place to go during intermission, but for next time when you don't have the 7-year-old. I always go there for halftime at Raptors games. Best bartenders are Jimmy and Compton.
