It was packed on a Saturday evening when I went with a group of 4, but luckily I called around noon to put my name on the "waiting list". This waiting list doesn't gurantee you a reservation but let's you somewhat jump the line. The place was packed, too packed. I also felt the washrooms (men's) was far too small to accommodate the crowd the location brings in (note: other Jack's have much bigger washrooms). The service was bogged down but pleasant. I ordered the chicken wings, but wasn't impressed with how greasy/watery the sauce was.
If your planning on watching a sporting event, know that they don't put on the game's audio, rather they pump loud Top 40 stuff.
Not sure I'd go back, lots of other places around the area. However the patio overlooking "Toronto's Times Square" looked peat neat.
