Ok not quite as old as the Caffe Reggio for instance, but Omonia Café opened in 1977 when a young John Arvanitis immigrated from Greece to New York. Since then, it has glassed itself in in winters on the corner of Broadway and 33rd Street in the heart of bustling Astoria and added Omonia Cafe-Next Door and Omonia Café in Bayridge, Brooklyn. Known for elaborate desserts, traditional Greek pastries so sweet you need an espresso to counterbalance the sugar and it became famous for the cake they baked for the film "My Big Fat Greek Wedding." You can also have a light lunch, dinner here or breakfast and unlike American coffee shops and cafes, you will get a bill until you ask for it, so relax.
