Alumnus visiting with teenage kids — what to tour, where to eat?

I am a Class of 1998 grad… I used to get back to PSU every year for about 10 years after graduating for games etc. but haven’t been back since about 2008. I am taking my kids (13 & 15) to see Luke Combs in April at Beaver Stadium. They are both interested in going to Penn State because of course I have talked about it since their births 😆… but I am sure a lot has changed. My son plays elite level hockey and we would love to visit the arena but it doesn’t seem that is possible? Also interested in the best restaurants downtown these days and any other tips. Thanks and WE ARE!
