MMoCA is a must-stop when on State Street. Besides the fact that they have intriguing exhibits (right now, for example, the Ellsworth Kelly Prints show is a wake-up call for your eyes with its bold color!), there’s also a gift shop with a plethora of wallet-tempting items you won’t find anywhere else as well as a rooftop sculpture garden (a terrific urban hideaway!) and restaurant (Fresco). Best of all: admission to the museum is free (though donations are certainly welcomed), and how often can you say that these days?
