Just to the south of Liechtenstein and round the corner heading east there is Meinfelden which makes some really nice wines. Some wineries are open Saturdays to try and buy.
But basically, almost everything in this neck of the woods is small and sleepy!
Here's a list of the 'top 25' - actually, it's probably a case of 'the only 25 things' http://www.tourismus.li/en/navpage.c...linLI&id=47707
My advice would be to do a 'round trip' and go and see Bad Ragaz / Pizol / Heidiland /Chur... http://www.heidiland.com/de/welcome.cfm
and there is a mining museum to see at Sargans - http://www.bergwerk-gonzen.ch/
Pizza-Bar Potenza
Herrengasse 9
open M-S 1000-2200
They only do pizza's nothing else.
Malbun is a nice ski resort (of course nearing its closure for the season), while the Fürstenfest on August 15th is a great party. For a day trip, I'd recommend taking the train to Sargans, hopping on one of their ugly fluorescent buses, and taking in the surrounds (Feldkirch +1 vote) and take the chance to tell people you've visited 3 countries within a few minutes! When you hit Vaduz, be sure to take in the Kunstmuseum and bask in the awe of the public art (I have never seen so many sculptures on one street!)
Incidentally, you can have your passport stamped in the tourist office in Vaduz. Much as this sounds like a nice idea, beware that it unfortunately says "tourist office" on the stamp - while it's legal, it could end up looking a bit odd in your passport for the next ten years...
