Food is delicious and you will find a romantic setting if you come for dinner! I'm giving ZuZu's 3 stars for the less-than-awesome service.
But last week when we stayed at Hotel Valley Ho and ate at ZuZu's (once for dinner, once for breakfast) it was not amazing.
Our waitress talked to us in a very condescending manner--she was much older, and it felt like she was talking down to me and my husband because of our age (we're in our 20s, and have been treated poorly at nicer places before in and around Scottsdale). It was super bizarre, and after dinner, I finally asked my husband if he felt the same way. Sure enough, he did. Next morning, a different waitress is rude and doesn't even offer to bring us coffee when we sit down. We had to ask her for coffee when she wanted to take our breakfast order.
Don't get me wrong, ZuZu's is definitely worth checking out if you are in the area or if you are staying at Hotel Valley Ho! I mean, the vintage-meets-modern decor drawn from the original property is so lovely and rich with history, and the menu is great with delicious food!
