I visit Cafe Nervosa on the regular.
I always take my mom here when she comes for a visit and have gone here with friends as well. Basically, my decision making process is as follows - I don't want to wander too far from home and Yorkville is ridiculously priced overall. Cafe Nervosa is not cheap, but it is reasonable.
My mom and I got delicious hand marinated olives, the arugula salad , a pizza with artichokes and olives, and two beer. It was more than enough food for two people and came to about $40. The food was good (I normally hate ordering salad at a resto, but it was worth it) and the price was right considering the yuppie location.
