What this place wants to be and what it is are a long ways apart. It is a fairly nice space. Superb artists come here to perform, likely drawn by the "socially responsible" setup as a training and employment place for Regent Park locals and George Brown students.
But suffering through the dismal food, beverage, and service offerings to hear great music ruins what could be a great evening. Reserving early and paying in advance won't even guarantee you can get a table where you can hear the music, let alone see the stage. Ignoring customers is an often used problem-solving strategy. I have a theory that the developer of the new Regent Park is filling a lot of the seats, because there seem to be exclusive reserved tables that are not available to the public, even when you have been told you bought the first tickets. Those tables get preferential treatment from staff.
The kitchen puts out a limited menu of fairly ordinary food. Nothing really wrong with the food, but if it wasn't for the music, I wouldn't go just for the food. Not much choice in beer or wine. And the wait staff haven't passed the spilling things, serving on the wrong side, and hanging their bums over your table while serving another one.
Look for your favorite musicians at other venues.
