Compared to average micro-breweries on the West Coast, Four Peaks is slightly below average. It probably wouldn't survive that long if they had to compete against their breweries. Having said that, they are probably the second best in Arizona (Oak Creek in Sedona is way better if beer is the only criterion). Their beers are consistently OK but sometimes their porters and stouts are a little skunky. Seasonal beers are good but I have never had a great one.
I like the building it's in but it sure is noisy when everyone is talking. They don't have live entertainment which may be a good thing since they don't need more noise. Unless you are there with friends it's kind of a boring place just to hang out, although there are plenty of cute college girls to look at.
Burgers are excellent. Service is OK but I usually go when it's not that busy.
