We went on a Saturday night. We got there at 7 and there was no line up to get into the place. There was a $14 cover charge which is super steep. It's not really worth $14 for a view of the CN Tower and for pricey drinks. We had to wait another hour to finally get seated. The drinks and the food were about $20 each which is quite expensive.
While the experience was enjoyable, I would only return if I was bringing a tourist to Toronto.
