Oh my Posh!
The service here was really great, so that's always a good start. I enjoyed our food although both of our seafood dishes were slightly overcooked, and my fish was overseasoned. The sweetbreads and kangaroo were both very well cooked and flavored. The presentation was clean.
I'd say the name is a little bit misleading as it's not really "improvisiational." To me, improv is just executing without prior thought. Based on what we ate, and what we observed being delivered to other guests, you can tell they had set dishes.
I really enjoyed my dessert which was a piped pistachio cheesecake with puff pastry.
I'd probably go back again for Restaurant Week since it's cheaper, but not sure if I'd go any other time. It was real, it was fun, but it wasn't real fun.
