This was outstanding. A couple of friends who live in Amsterdam took us here, and it was a fantastic choice. I have no idea how "authentic" it really is, but the chef is an older guy who comes out and tells you what's on that night's tasting menu before you order, which checks off a bunch of boxes on the "authentic" checklist.
The food itself was really great -- the tasting menu on our night was shrimp, red mullet + mixed seafood, duck, and a cheese plate. All four courses were outstanding. The shrimp was super soft and really interesting, the clams really stood out on the second course, the duck was fantastic, and the cheese course kind of blew us away -- I asked for the strongest ones they had, and they definitely came through, including a pretty stinky blue and a dutch cheese that was just excellent.
One recommendation: go with good company. It's roughly one course per 30-60 minutes, so you're gonna be there for a while if you do the tasting menu. We didn't mind this, but with a different group, we may have.
The food was really excellent though. Awesome spot. read more
