Burgers are really tasty, and chips actually refer to crisps which are delicious as well! With very few vege options in most restaurants in Lausanne I was very impressed by this place! Three vege options available and a selection of cordials and extras.
What I liked as well was that almost all products are locally produced and the staff are very friendly. (If you revert to English they don't bat an eyelid!)
It is a small location so there are not many places to sit down, but takeaway boxes are useful and made of cardboard so easy to eat from and there is a park nearby to eat on a warm day. If you want to sit down be there before 12.30 as that's when the most people come.
Go visit and enjoy!
Cons: Small place
