Our concierge at the London helped us make a last-minute reservation here, although it looked like we didn't really need it by the seating on a Friday night. The service was excellent, and the atmosphere was exactly what you'd expect: clubby, loud, dominated by the after-work happy hour crowd. The steak itself was so well-prepared that it didn't need any adornment; the flavor came through just from the cooking. It was lightly seasoned, and the meat really lived up to that treatment.
One further note on atmosphere: we were surprised by the number of families we saw there, given the overall vibe of the place and the prices. At least half the tables on Friday night had children, even very small children, at them. It didn't bother us, but it did surprise us.
