304 was neat, I think in part because this side of the upper deck kind of feels like a home run porch similar to what the Texas Rangers have at their ballpark. Not that a player could actually hit a home run that could reach these seats although Coors Field does give up an awful lot of home runs.
The only thing you can't see from our seats (row 14) was the warning track. We were just too high up with too many other seats below us. Our seats were comfortable though, our section was for the most part empty, we could have sat wherever we wanted but decided to stick with the seats we purchased. (On Stubhub).

Outside of section 304, you won't find much variety in terms of ballpark food. The two stands outside of our seats were called Grille Works and then the other was called Fan Fare. They will both have all of the basic food items that you would expect but if you want something exotic like the Todd Helton burger, you will have to move down to the bottom level and eat at the little diner they have dedicated to him. You can bring your own food into the ballpark if you're on a budget and the only thing that I think could make the Coors Field experience better would be if they actually allowed tailgating in the parking lot. The Monfort Brothers must not like tailgating.
