At dinner in the hotel in Zurich, Miss kenju ordered a hamburger and this came with it. Doesn't it look like a tube of toothpaste? It is actually mustard. I couldn't believe it was packaged in a tube, but think how functional that is! I am impressed. In the US, we have clumsy little packets of mustard that you usually spill all over yourself when you are trying to open them. No such problem with this little gem!
