For some strange reason their veggie burger is vegan but the bread isn't! Only found this out after I ate there the first time (I asked if the burger was vegan but didn't think to check the bread and they didn't mention it) and then came back again, as it's a decent price (for Switzerland) with nice flavour combos and good quality ingredients. It also has 3 different veggie options and particularly good chips.
So, good for vegetarians, but vegans stay away unless you don't mind a bunless burger.
Cons: Rubbish Vegan Options, Pictures Of Grinning Cows Everywhere
