We went there on wednesday in order to benefit from their special vegan day but we didn't find anything that was labelled vegan. We have to asked the waiter to indicate us what were the vegan ice creams but he has hesitated before showing us their homemade water ices.
In spite of that problem of labelling, they have a good number of vegan water ices: melon, peach, orange, raspberry, etc. They are tasty and not expensive (2 euros each). However, they are the only vegan thing that you can eat on that bakery.
Cons: no other vegan options, vegan water ices not clearly indicated
