Honestly, this will probably forever be my worst higher end dining experience. There was nothing even remotely redemptive about Arrowhead Grill. The service was, well, basically non-existent, the steak was inferior to that of, umm, pick any fairly cheap chain steakhouse, and it's not even much to look at.
Save your money and go to any of the other amazing steakhouses in the Phoenix area - Ruth's Chris, Donovan's etc. Avoid. I'm pretty sure the people who have given this place a good review have never tasted a perfectly prepared steak before.
