This is a nice addition to the neighborhood, especially since losing Paper House Party Store - they have a great selection of cards, wrapping paper, party goods, and general merchandise.
We picked up a fake christmas tree plant that's perfect for a small city apartment. They had a full aisle of christmas cards, and many loose ones, also for birthdays, etc. If you need any kind of party goods, this is a good resource.
They have a few toys for kids, too. Finally, a store on 86th street that doesn't duplicate one that's two blocks away! (i.e. Starbucks, electronic, gifts, etc.!)
