Fantastic double B's!
Carens like many Yelplers have mentioned is probably one of the least expensive and less pretentious places in Yorkville but hey, it is still not really cheap.
I really like the ambience at Carens. You'll find a corner that suits your mood. If you like people watching, sit at the front patio. If you like a bit of privacy head to the back patio. And if you want total privacy and a more romantic setting, sit upstairs. Of course, there's not such thing as privacy at Carens whenever it's packed, especially on the weekends.
Pretty decent selection of red and white and if you don't know much about wine, the staff are really helpful. The cheese is also good but I'm not a huge fan cheese platters and if you're like me and just want an appetizer with your wine, I highly recommend the baked brie. Simply the best double B's I have ever had!!
