I like Zuma and I don't think it warrants such a negative rating. I've been a fan of Zuma since I started school at ASU and I was only able to go for the food. I really enjoy their grilled cheese sandwich (plain, I know!) and also they have a great appetizer that is a tomato stuffed with either tuna or chicken salad. Definitely one my favorites.
Mainly, I like zuma because the bartenders and staff are always very nice and accommodating. I never have to wait for a drink with them and very often they are pretty giving with generously poured drinks and occasionally a free shot or two for myself and my friends. They also have a fabulous ladies night on Wednesdays where they have free food and champagne for girls (yes, it's not fair boys complain complain complain but you guys get plenty of perks in other industries!). Favorite bartenders are Tommy Tau and Mike!
