I've been to several games at Lambeau and it's a great place to see a game. The tailgating there is at an entirely different level than any other place that I've been to and the intensity level inside the stadium is very special. I've never seen the Packers play against our 49ers there, but the cheeseheads will mostly be friendly to you – don’t worry about wearing 49ers gear. You're going to have a good time there if our team can get its act together and take advantage of a struggling Packers team - their O-line is even worse than ours. If you get the opportunity before or after the game, be sure to make your way over to Kroll’s West (opposite the west side of Lambea) for some butter burgers and chili (poured on top of spaghetti). My wife’s from there and she’s wild about both of them; I’m mixed on them, but it is the signature eating experience in Green Bay.
