proof on main , the restaurant attached to louisville's popular (and awesome) hotel/art gallery 21c, is filled with funky and funartsuch as a metallic green walrus, a projected video of a person eating from an oversized bowl and spoon, a painting of a woman walking on water, and a wall-mounted elk head made entirely from old shoes. given the avant-garde artwork, i expected that the restaurant would serve innovative cuisine to match; so, at my recent visit, i was a little surprised by the rather traditional menu. aside from the artwork, the dining room, too, was fairly typical of many high-end restaurants - white tablecloths, candles on the tables, subdued lighting, and so on. there's absolutely nothing wrong with that, but i felt like the restaurant couldn't quite decide if it wanted to be contemporary and cool or traditional and formal. this slight confusion was also reflected in the clientele, which seemed pretty evenly split between hip, young foodies and overdressed older folks.
