Last Sunday we had brunch at La Ferme du Chateau.

It was delightful! It is set up in such a way that you are able to keep an eye on your children while seating at your table and enjoying the company of your friends and/or family. There is a square yard with tables around the perimeter and then several farm related rid on toys, a swing set, and a playhouse with slide. In addition, there are many fun animals and birds for the children to see - a parrot, llamas, peacocks, and more. The shade availability is also great, which is sometimes a hassle to find for newborns and infants not yet allowed to use sunscreen.

I will say that the food was not necessarily "amazing." Your standard fare of different breads, cheeses, yogurts, eggs, croissants, etc. It was not bad by any means, just nothing spectacular. However, when considering the fact that I was able to leisurely eat my meal and talk to friends for hours without my toddler or infant pitching a fit, they could have served a crap meal and I'd probably still go again.

Anyhow, two thumbs up. Now I just need to find the equivalent experience in Canton Zurich.
