At the new Grass Fed in J.P., we order a regular hamburger, fries, the Blue Devil, onion rings, and a chocolate shake. The burger, promised pink, is overdone, hard, and tasteless. The bun is gummy. Fries are crisp in spots, barely cooked in others, onion rings are burnt all over, and the Blue Devil, with Stilton, bacon, and aioli, has another dense overcooked patty, but is saved by luscious cheese and smoky bacon. (What dish isn’t significantly improved with Stilton and a crisp rasher?)
