We weren’t around back then, but we imagine that, with vinyl on the turntable, lava lamps in the corners, and an abundance of weed, the ’70s were the golden age of hanging out in basements. The Groove, a cocktail lounge inside of Hojoko, isn’t in a basement (in fact, it’s got wide windows that open up directly onto Boylston), but a ’70s basement is exactly what it feels like in the best way possible. There are cream-colored lamps, overlapping rugs, bead curtains, and yes, a turntable - though sometimes there’s live music. If you’re hungry, there are small bites and snacks to go with the cocktails, like nachos topped with torched hamachi, and you also have the option of ordering off the main Hojoko menu.
