We ate there last August before it became a "signature," and while we really enjoyed the meal, I am horrified by the increase in prices to justify its new "signature" status and won't recommend it based on that.
I don't see how they could have improved the food and atmosphere enough to charge the new prices. From every report I've read here, the tables are still on top of each other. I've read conflicting reports about the beef quality--i.e., whether it's prime now or not. I wouldn't pay what they're asking for non-prime beef, I'll tell you that!
