This won't be a rant or rave about the team, the fans, or management. I'm going to reveiw this as an activity/night out for the family.
Action: The team was right around .500 this season so most of the games were quite good. They do seem to play up for good teams and down for poor teams, so the games usually are well fought (which for die hard fans would be irritating, but for someone that just wants to see good hockey it's actually a plus).
Value: For a pro sport, flat out awesome. You can get seats in the upper deck for right around $20-$24. We usually sit up there and you can see everything just fine. We've walked around the stadium a fair bit and have sat in several different places... I don't think there are many bad seats in the house. Souveniers are flat-out expensive; you can find the same items (or almost the same) online for about 50% of the in-arena cost.
Ambiance/environment: Good enough so you can bring kids. Stadium is clean and well kept. The resturants just to the north are great and lots of people go there before the game for a drink or some food, and there are some decent places there.
Food: Not bad for an arena. Definitely doesn't count as cheap, but not outrageous. The difference in cost is small enough that that I recommend buying the premium beer over the Bud Light/Coors Light/meh beverage.
Location: Gets low marks for being way out in Glendale and recently instituting parking fees.
Overall: Definitely worth going to see. The team is young and has several good players on it. It hasn't really taken off in popularity yet but attendence has gone up on average the past few seasons. I'd recommend going to see some games now, as signs do point to a good team in a few years and likely higher ticket prices to go with that.
