My husband, an avid Chowhounder from L.A., will be spending 9 days in Toronto on business. What are the spots not to be missed? He'll be staying in the downtown east area and has an eclectic palate, with a special love for cheaper ethnic food (although the occasional fancy meal is great, too!) This trip has come up unexpectedly and we have no knowledge of Toronto food culture -- tell us what it's all about, hounds! What would he be a fool to miss?
