Things to do Indoors in Lancaster, PA/Restaurant Recs

[applecrispy]

DH and I are celebrating our 10th wedding anniversary and doing a 4 day trip down to Lancaster, PA. I planned out a ton of things to do but unfortunately it looks like it will rain for most of our trip. Any suggestions around/in Lancaster? We don't drink alcohol so the wineries are out. Also we are looking for a nicer place to eat dinner for our anniversary dinner. Neither of us eat seafood, so that's out. Thank you!

I don't have any recommendations for restaurants - we were with our kids.
