Went to Dersou last week, which was awarded "Best new opening" at the recent Omnivore Food Festival. I got their 90 euro no-choice tasting menu, which included 5 courses paired with 5 different cocktails, and an amuse-bouche that was more like a course in itself. I really loved it and am excited to go back again soon. 90 euros is of course pretty pricey but when it includes that many cocktails, it kind of makes sense. I want to go back and just order a la carte, or go for lunch. Overall, I was really impressed.
