Seems like nobody likes the new version of Yankee Stadium. For that matter, people are pretty ambivalent about City Field, home of the New York Mets, too. At least, according to 'research' done by Nate Silver of the New York Times.
Silver did not exactly do an exhaustive study. Rather, he went to the review site Yelp.com and figured out how reviewers on that popular site ranked baseball stadium. Citi Field came in 15th, while Yankee Stadium came in 21st of the 32 major-league ballparks.
The best, according to the reviewers? Pittsburgh's PNC Park, followed by Boston Fenway Park and At&T Park, home of the San Francisco Giants.
No clue how Fenway got in there, unless the reviewers are just sentimental. It's old, crowded, insanely difficult to get in and out of and generally not comfortable.
As for the New York stadiums, I am not really qualified to say much about Citi Field -- I have not been there yet. It looks gorgeous on television, but the Mets did make Detroit's Comerica Park mistake. That is, they built a cavernous outfield that is simply way, way too spacious.
Yankee Stadium is a great place, much more modern and convenient than its predecessor across the street. Yet, despite the creature comforts I am a little disappointed by the place. I have been there a few times, and it just doesn't have the personality of the old place. It's pretty much a sterile building. Fans are much farther away, and with all the empty seats for the rich folks unoccupied close to the field it is much quieter than the old Stadium. Monument Park is an atrocity that can't be seen by most of the ballpark, and designers did an abominable job figuring out an entrance and exit to the park. The only way in finds a line of people pretty much blocking a main walkway. The restaurant in center field, which blocks seating on both sides, is also a joke. Unbelievable that is this age of technology designers could not build a restaurant that did not obstruct views.
Anyway, there you have it. Not much love for New York's baseball palaces.
