"L’en-Cas Bio is a casual place where you grab cold beverages from a case, put them on a tray, order food at counter and pay, sit down, and they bring you your food. A restaurant with organic vegetarian and gluten-free options sounded great in theory, but my actual experience disappointed. The food tasted good, but poorly trained staff made me worry that my food would not be truly gluten-free. Cashier wasn’t sure what was gluten-free and what wasn’t, even though there were signs differentiating right behind her head. When my food came, salmon and leek cake looked like slices of a mini-loaf. Salad, which I had not ordered, had half a slice of bread on it. So I inquired and the cook told me nothing on my tray was gluten-free. I protested that gluten-free was what I had ordered and their sign says the salmon and leek cake was “Sans Gluten” and I showed him the sign. He said oh yes, that was right, he was new, sorry. He told me the slice of bread on the salad definitely had gluten in it, but he did not replace the salad. The salad turned out to be shredded cabbage. The salmon cake looked quite yellow, so I’m guessing it was made from corn. I did not eat it all since many celiacs, including me, do not do well with corn. I felt really lousy afterward. Can’t say why exactly though. As I mentioned, the food was tasty, but if you seriously cannot handle gluten, I'd be careful here.Quite expensive for what you get. The tiniest Perrier bottle on the planet was 2,20. Fresh fruit juice (which I did not get) cost 6 euros."
