This is my backup place for the dessert fix when I can't tread all the way midtown to Rahier (they do carry desserts from Rahier BTW). The place is relatively tiny for grocery store but they do have a lot of variety. Its is pricey for sure kind of like the places if you have to ask you probably can't afford it (3$ for single biscotti! really!)
They also sell the butter tart from maid's cottage (legendary) Good cafe and and place to see and be seen if you want to hangout in Yorkville.
