Oh how time flies! Opa, the stylish, Midtown Village Greek restaurant and bar that the brother and sister duo of George and Vasiliki Tsiouris brought to life, is celebrating its second anniversary on Sunday. Seems like it just opened yesterday. In honor of this milestone, they are offering up the majority of their menu (mezedes, drinks, beer) for just $2. The everyday a la carte menu will also be available, but at full price. Here’s hoping Snowmageddon II spares us, and doesn’t put the kibosh on the festivities.
