Went there for the 49ers game yesterday. Besides the fact that the Panthers finally won, we thoroughly enjopyed the whole stadium experience.
It was the first time my 5-year old went to a game so I was nervous about keeping him interested and engaged throughout a 4 hour football game in a 80F heat. But everyhting in the stadium got him so excited, that the time went by in a flash.
We really liked the Philly Cheese steak, the BBQ sandwiches and the fact that you have "real' beer choices (draft) like Stella Artois etc, not just bottled Miller Light...
Is it expensive? Sure. $4 for a bottle of water and $7 for a Stella is a tall order and we probably went through $80 for the 4 of us (without the actual tickets ;-) throughout the day.
But I view it as a special event that we do maybe once or twice a year so from an entertainment value perspective it is definitely worth it to me!
