Checked out Diva on a Monday night as part of Dine Out Vancouver 2009. A nice place, apparently re-modeled (but I hadn't been there previously), just off the lobby of the Metropolitan Hotel Vancouver.
Food - I would describe our dishes, not so much as "meals", but as "edible art". I had the Coconut Curried Milk & Yam Soup to start, which was fantastic, but a fairly small portion. My main was the Seared BC Albacore Tuna and dessert Caramelized cheesecake. The main was decent, and the dessert was phenomenal. I also had an "extra course" of Pan-fried scallops which were absolutely incredible.
My girlfriend had the Brandade Salad, Braised Beef Shortrib and the Chocolate Desserts. The Espresso pot de creme (which came with the chocolate) was probably the best dessert I've ever tasted in my life. Amazing!
Service - Our waiter was excellent. Exactly what you'd expect from this type of restaurant. My girlfriend loved that he referred to us as "the lady and the gentleman". Drinks were promptly served and re-filled. Though food service was a bit slow, I enjoyed the relaxed pace, which fit in quite nicely with the comfortable, intimate setting.
Ambiance & Value - Not a great value; small portions for a higher price, but that's to be expected. Ambiance was nice. Candlelight, soft music, open-style kitchen, and a beautiful bar.
