Happy hour is a beautiful thing. And nothing goes better with happy hour than sliders, which are filling but not too filling, with just enough protein and carbs to cushion the alcohol without ruining your dinner. The brains behind the Kitchen Next Door know this, which is why the community-hour menu — served daily from 3 to 6 p.m. — includes three versions for you to mix and match. In true Kitchen style, the cheeseburger slider is made of local beef, the slow-roasted pork is accented with salsa verde, and the vegetarian option is a cut above the rest — made not with brown rice and mushrooms, but ruby beets jazzed up with feta, balsamic onions and arugula. The only thing to say when your sliders arrive? "Cheers." And when they're gone? "Another round."
