All hype and no substance. Our reservation was secured by the concierge at the Four Seasons and we were assured that GR Steak was 'the hot restaurant'. Upon arrival, our party of 4 was ushered to the bar area for what was supposed to be a 10 minute wait. 45 minutes later, our table was ready. Needless to say, we were ready to eat. Only a waiter never materialized. Odd, considering all the staff floating about. Another 10 minutes without any staff interaction and we were on to plan 'b'. Thank you Four Seasons and Mesa Grill for saving the evening!
