I had the special Swiss sausage, Servalas. Apparently it's made from the intestine of special Argentinian kind of livestock. Switzerland recently joined the Schegen states (like the EU but not), which ban this kind of import, so there has been a lot of hullabaloo about how to continue authentic production of the sausage. It didn't really have such a distinctive taste in my opinion, but sausages are generally tasty anyway. I love how hullabaloo is not listed as a spelling error.
