Had some at Comme Ca a few years back. Went with a couple chef friends - who ordered the skate and (he's tough) thought they did a good job with it. Pretty sure it was French style - crispy with Grenobloise.
The skate Grenobloise at Brasserie Vert in the Hollywood-Highland complex is pretty tasty: sauteed crisp in browned butter and garnished with tiny croutons and bits of lemon pulp. Call first to see if it's on the menu.
