The festival is now, until next Saturday (Saturday 02.04.2011)
I was there today (Sunday 27.03) with my wife and daughter (2.5 year old), it was great for a first visit to this village. It's an other one of those beautiful-little-village-of-Lavaux-with-superb-lakeshore-medieval-streets-and-nice-bistrots, and there is even much more for one week. I really liked the pleasant feeling of a festival well organized and fit for the place.
I and family will go again next Saturday, even if it rains! We also hope to go there one evening this week after work; it should be so lovely if the weather is nice. And, who knows, I may even hear some live band, despite my total lack of interest for jazz music
