In New York City, home to countless steakhouses and chef-driven burgers, a few chefs are pairing high-quality burgers with a classic martini, a cocktail generally associated with steak. These aren’t fast-food-style burgers; instead, these burgers are generally thick, made with custom beef or dry-aged meat, and certainly not cheap.
