I'm at ballpark #27, Coors Field and it is one of my favorites. I've heard that Citizen's Bank Park designers used used aspects of Coors Field more than any other park.
Walkind down the row of restaurants in left field feels like Ashburn Alley. Lots of interesting food options including 6 different foot long hot dogs, Denver's version of the cheesesteak (it didn't look bad), rocky mountain oysters, gelatos, and strawberry ca-bobs (huge strawberries alternated with frozen cheesecake drizzled in chocolate.) I went with the Elk Brat.
The Rockpile seats in centerfield look really cool.
