I went to Upstream with a couple of friends for restaurant week last night. The food was nothing spectacular, especially for the price (which had an added supplement for many of their appetizers and entrees). Our wine glasses were covered in dust and had water droplets on them. They hadn't been cleaned properly. The wine specials that they had all tasted as if they were very low quality.
I had the Salmon, which tasted good, but again it was nothing special for the price. My friend had the Sea Bass, which is supposedly their specialty, but it came out way undercooked and they had to bring out another one.
Overall this place is overrated...maybe they just couldn't handle the volume from restaurant week.
