This year’s Rookie of the Year at the Vendy Awards, the popular Souvlaki GR truck, was supposed to debut lunch service today at noon at 21st Street and Sixth Avenue. Unfortunately, according to their latest Twitter update, a parking snafu has caused delays. But, fear not, tzatziki heads. If you miss them for lunch, you can always catch them for dinner at the Randolph on Broome tonight. The truck will be parked outside the bar from 5:30 till the wee hours, with half-price cocktails inside.
