Romantic dinner for anniversary - Zürich
I have my anniversary soon and I would like to prepare a special dinner for my wife, I was thinking on a dinner in a boat on Zürich's lake, but I don't know how possible it is. If that is difficult, at least I would like to know about a beautiful place/restaurant. I don't mind to pay a little bit more than usual, but I would prefer to avoid really expensive places (Switzerland is expensive enough :-) ).
Thanks in advance!
