The only positives about this restaurant is gorgeous 360 view of Toronto (it takes a little over an hour to completely rotate) and the complimentary access to the observatory deck with the purchase of an entree. The overflowing wine cellar with the glass encased Hennessy Louis XVIII Black Pearl was a nice touch as well.
Other than that, it's not worth the hype. The boyfriend and I both partook in the $75 pre-fixe menu and we were both extremely underwhelmed. The amuse bouche wasn't worth the extra $10 over the $65 pre-fixe menu. My peppercorn steak layed on top of yukon gold mashed potatoes tasted mediocre, even after adding fresh ground pepper on top. The lemon tart for dessert tasted good... but nothing out of the ordinary. Each soda/juice refill is at a cost ($4 per refill). Service was spotty throughout the night and the food took a long time in between each course.
The atmosphere is fancy, but the dress code is casual. A individual ticket to the CN Tower is about $30 for general admission, so paying an extra for a 3 course meal with a rotating view of Toronto isn't such a bad deal. (Be sure to request a window seat when making your reservation)
