Hi guys, newbie here. ; w;

I have some questions, I have an upcoming flight on the 15th TPA-MSP-FNT/FNT-ATL-TPA on DL, and I have a 3 hour layover in Minneapolis, I want to know if there are any 'must do' things in MSP? I know the observation deck is there, is it still open? are there any shops with model airplanes for a decent price? I'd assume there would be...
Oh, and is there any special place you recommend to get a bite to eat?

Well thanks guys, It's much appreciated!
