I think Four Peaks has that nostalgia factor for me. They don't have the best beer in the valley but there's something about their large wide-open space with the brewing tanks in the back that just 'feels' right. The dim lighting at night adds to the vibe.
The food is pretty good for a brewery if your looking for standard american fare (ie. burgers, fries, wings). Prices are reasonable on both beer and food and portions are filling.
If you're a beer snob (like me) there's definitely better breweries and beer bars in the valley. But if you just want to kick back with friends or family, eat some solid food, and enjoy some drinkable albeit average beer - this place won't let you down.
