This under-the-radar stand-up venue comes to life from Thursday through Saturday. "It's the kind of thing you stumble upon and find yourself blown away by the talent that's lurking in . . . a Howard Johnson," says Benny Boshnack, who started Grandma's Basement more than two years ago.
Friday and Saturday showcases cost $5.
