I plan on pushing it for the 2 and a half hours. Is there anything I must see in that time, food/beer I should try, souvenier shops with good stuff to bring home etc..? I will make sure I check in electronically the day before to get my boarding pass and I will only have a carry-on. Thanks for the suggestions; here I was planning on spending my time at the airport and now I will get a tiny taste of Switzerland!
