Thank's to Natalie T.'s UYE, I finally came to Nota Bene!
I had the Jennifer's Burger ($22), with caramelized onions and blue cheese with fries on the side. The burger might not look all that big, but the patty seems to be handmade and is extremely thick with sauce and herbs for flavouring directly in the patty, which made it tasty and filling. The caramelized onion was the perfect pairing for the burger (no vegetables inside) but I wasn't a huge fan of the blue cheese. Next time I'd ask for it without or with substitution. I asked for the burger in medium and it's a lot redder on the inside than I had expected, partly because the burger was so thick. It didn't taste raw though. I don't have much to say about the fries on the side, since I'm not a fries person.
I had the opportunity to try the duck salad (REALLY GOOD) and the rabbit pappardelle, which was really flavourful.
Very enjoyable meal with very good service. I'm not entirely sure the high price tag is justifiable though, as average entree price was about $30.
