Yesterday, the Papa John’s pizza giveaway. Today, news from Opus that the gluten-free Upper East Side Italian newcomer is offering free slices every day through the holidays with the purchase of a drink at the bar. Not quite as generous as the free personal pizza you get with a drink at Alligator, Crocodile, and Charleston (especially since the deal is only available between 5 p.m. and 6 p.m.), but if you want to partake in a slightly less grimy environment, there you have it.
