Dos Toros isn’t the only drunk-food chain adding a westside outpost to its downtown and Williamsburg locations. The Meatball Shop, which started on the Lower East Side six years ago, opens its seventh location in Hell’s Kitchen today. This one comes with a brighter, cleaner design and an adjacent bar. The bar as tastefully named as you’d expect from the guys whose mantra is “EAT MY BALLS” and who offer BALLS t-shirts. They’re calling the place Sidepiece.
