Casa oliveira is one of my favorite little wine shops in the west village. I usually look for good value, mid-range price wines ($10-20) and they have a great selection. The staff is really helpful and knowledgeable, and they have the best hours of any store in the area (open to midnight every day except sunday - great for a last minute run late on a friday night). They also have a good range of mid-to-high quality liquor and champagne. The location is convenient as well, just a block from the christopher st stop on the 1. Would recommend to anyone in the neighborhood.
Pros: excellent variety of good-value wines, great hours
