There's a pub by the brewery, but about the only thing going for it is that they serve Creemore. It's pub food, and somewhat crappy at that.
There's at least one fancy restaurant - dinner only I think - haven't tried it.
There's a catering/cooking class/cafe place with baked goods and prepared foods, they will pack you a picnic if you want it. The few baked goods I've tried here have been fine but nothing mind-blowing. The pretension of the place doesn't really help.
My general impression of the town is that it has out-yuppified itself way beyond what it actually has to offer. But I do love that beer!
