La Banane, Quetzal, Osteria Julia, Bar Isabel...?

One of my friends from NYC is coming for 2 days and I've booked Quetzal and Osteria Julia for dinner. I'm wondering if there's any better place? How is Bar Isabel and La Banane? Mineral? I've heard mixed reviews and I'd really love to show my friend the best upscale dining Toronto has to offer. Appreciate any advice!
