T Rex, which used to be called the Rex Hotel and was a favorite spot for the downtown liquid lunch crowd, has grown over the last twenty years into one of Toronto's most ecclectic and popular jazz venues.
A launching spot for local artists and a visiting stage for international ones, the T Rex never has a dark night, usually averaging two sets on weekdays, three on weekends. Although their drinks can get a mite expensive, they're well worth the funky atmosphere and auditory pleasures. There's a heck of a lot of variety on tap.
Get there early; the place is brimming by 9:00.
