I have been to Omonia Cafe many times; it is one of my favorite places to grab dessert in Astoria. You really have to appreciate a place whose menu for desserts is almost 4 times the size of the food menu. Besides pastries or desserts they have a unique selection of coffees. I can not really pick a favorite dessert there, because every time I go I try to get something different, but their Baklava was amazing. They are also open late so you can hit this spot after the night out.
