I went to Seasonal for a work dinner the week of December 3 with a party of 6. After looking at several other restaurants in the area, we settled on Seasonal based on the reviews here, and we were definitely not disappointed! It was a bit of a risky choice for a holiday dinner with clients - Austrian is definitely not standard holiday fare in NYC! However, from the moment we walked in the experience was fantastic. The bartender (whose name escapes me, but she was friendly and very helpful) was happy to explain the menu to me while I waited for the rest of my party to arrive, and even gave me a taste of one of the specialty cocktails. Delicious.
Our party all opted for the 3 course tasting menu, and the sommelier suggested a really nice Austrian red to go with it. Between the 6 of us, we tried all of the options available on the menu, and every single one of them was beautifully presented and very very good.
Definitely a different night, but in a restaurant with great atmosphere - classy, but not stuffy - and exceptional service from start to finish. I'm very glad to have stumbled upon Seasonal!
