Hey Puck,
I was at the new Yankee Stadium last summer and I have to say I'm not a fan. It didn't even strike me as a ballpark, more like a huge corporate collosus with no soul. Just like the Yankees though...so it fits at least. The tickets are extremely expensive and I agree with one of the other posters who said they don't have any good food options. (Really, they couldn't have had at least one good option after spending a billion?) There were two redeeming things about the place in my experience. Monument Park was pretty cool, get there right when the gates open because it closes about 45 minutes before the game. The line was long when I was there, but it went fast. And their HOF/museum was quite nice. I think that is open during the games too but I can't exactly remember. I didn't make it to Citi Field but one weird thing I remember about their tours is that they were only offered on Saturday and Sunday. I thought that was weird that they wouldn't at least offer them on Friday as well during the season when the team was out of town but maybe there's a reason they are limited to weekends. Hope this helps, enjoy NYC!
