BLTs, R.I.P. Photo: Kate AttardoWe’re saddened, but not surprised, to learn of the demise of Schnäck, the Red Hook hamburger-and-hot-dog mecca that was one of our favorite additions to the Brooklyn restaurant scene — nay, to American vernacular cooking! Co-owner Harry Hawk tells us that the end is nigh, but he will not give an expiration date. We hear through the grapevine that the proximate cause of the closing is a lost lease, but having seen ever-thinning crowds over the past year, we are more likely to believe that the poor location and awful service softened the victim up for the final blow. Schnäck is a resilient entity, however, and it would not surprise us to see it pop up somewhere else; in the meantime, Schnäck burgers, or their near equivalents, will continue to be available at Water Taxi Beach in Long Island City.
