We suspect a young boy owns the establishment that makes this city's best chocolate mousse — not because mousse is akin to pudding, and that's what's often packed in Lunchables. You'll see why, once you visit this hideaway featuring Belgian cuisine. Festooning the cafe's walls are dozens of pictures and other likenesses of boys and cherubs holding their penises. Some are peeing. Must be a Belgian thing. We shrug as we wolf down the creamy concoction so strong and rich it's like eating Scharffen Berger with a spoon. If you can stomach the art, stay for dinner. The mussel dishes are divine, and they come with French fries (which just may have been invented in Belgium).
