There’s a lot to like about the Walker Art Center’s recent renovation and the opening of adjoining restaurant Esker Grove, including the fact that Cityview Bar is now available as a casual hangout space before and after shows at the McGuire Theater. It’s a far more appealing and accessible place to grab a drink than the old Balcony Bar, and can we. Talk. About. The. Bathrooms? They’re sleek and minimalist, hushed retreats that feature gapless, four-wall privacy in the stalls. They may not be show-offish like the Varsity Theater bathrooms, but if there’s ever a place where form should follow function, it’s in the water closet.
