I stumbled upon this spot after going for a run in central park with my friend from DC. We were looking for something quick to eat and randomly picked Amber. It was a Saturday, late morning/early afternoon and they had a weekend brunch menu, which included two drinks with our meal! I ordered the Curry and my friend order a sushi/sashimi combination. I must say this was a solid find in the area. The sushi was fresh and delicious, the service was fantastic, ambiance was cozy and modern, and the price was very affordable (by NYC standards). Additionally, the tasty drinks were an added bonus to an already solid meal.
Overall, I really enjoyed Amber on the Upper West Side and I would recommend it, if you are in the area.
Enjoy!
