Chase Field is the home to the Arizona Diamondbacks (or Dbacks, I should say). It's a rather nice field, with a good amount of seats and multiple levels.
Located in the heart of Phoenix, this stadium became famous when it was first built. Having a moving roof to let the sun in (or keep the rain out) was something unheard of at the time. It is still a thing of wonders.
I've only been to a few games here, but each time that I have come, I find that the experience is good. It usually does not completely fill up (it's pretty easy to find seats together if you are going in a group), and it makes for a great family getaway.
I would not exactly suggest that you plan on eating a full meal here... Prices are expensive, and the quality of food is not that good. I would recommend that you eat outside of the stadium, and save room for a few drinks when you get inside.
If you have lived here for 10 years, or if you are just passing through, make sure to stop on by and see the magnificent edifice for itself.
