Boozy ice creams and popsicles have become a popular choice for grown ups trying to cool down on hot summer nights. Over at Pergola in the Flatiron, on Friday from 11 a.m. to 8 p.m. they have a new pop-up "adult lemonade stand" serving Petal Pops from FrutaPOP made with elderflower, lemonade and spiked with some Tito's Vodka. The pretty pops, which are also made with edible flowers, are available for $8 alongside Chandon 187ml bottles and Wolffer Estate Cider No.139 Fridays through Labor Day.
