Hello Natacha🌻 We are a fully vegan place, we only share the display with another one to reduce cost and make the food more affordable to people. We have a full vegan menu and the sandwich you got was probably the last on that day because the only thing we prepare beforehand is the cold sandwiches and they run out rather quickly early in the morning. Everything else on our fully vegan menu is prepared fresh, in seperate kitchen, on a different floor by special chefs. We apologize for what you saw in the sandwich, we were having a display fridge problem that our cashier noticed later and we handled his incompetence directly. The sandwiches are prepared daily but this batch had olives in the bread that went bad on the day because of the heat problem. We would love for you to come back and try our menu and we're sorry again for your experience.
