A resto on the 40th floor...should be some excellent views from up there. Interestingly enough that's now the third high-rise restaurant recently proposed. The Dorian is going to have one on the 26th floor, and there is one proposed for 1520From the project website:
"Slate, with its partners Oliver & Bonacini and Concorde Group, are creating three singular dining concepts at Stephen Avenue Place: a panoramic 40th floor world-class restaurant, a 2nd floor chef-driven, market-style Food Hall and a stylish and animated ground floor restaurant, patio and bar."
Oliver & Bonacini is the same group that did that restaurant on the ground floor of The Bay so I'm guessing it will be a unique one-off concept and not any chain.
