Next Thursday, soft-opened Two Boots Tavern will officially introduce itself to the neighborhood with a party featuring the music of neighbor Eliott Sharp (there will be live performances weekly) and — take note, people — free slices. Owner Phil Hartman will also unveil his long-awaited Luisaida pizza, named after Luis Guzmán, who may just make an appearance (all Hartman will tell us about the pie is that it’ll be spicy and will use ingredients from the neighborhood— we’re going to venture a guess that he’s talking about pickled peppers from the Pickle Guys). In about a week, there’ll be a list of cocktails (also named after Lower East Side characters and institutions) and at some point, a shrine to Bill Buckner, the Red Sox first baseman who handed the World Series over to the Mets in 1986. Hartman also says the Hell’s Kitchen location of Two Boots, on Ninth Avenue between 44th and 45th Streets, should open within a month. Sorry, no booze there.
