The so-called LES Kitchen is almost ready to roll. As noted, the new burger joint has been prepping 15 Essex Street in the wake of the Juicery’s departure last year.  The menu sitting in the windows serves as hype material for the new establishment. Here’s what to expect when they open at the end of the month. It’s clear that LES Kitchen is a no-frills burger joint, serving Pat LaFrieda beef alongside pickles from the Pickle Guys.
