I came for the macaroons. They are expensive and worth every bite (the chocolate orange one is worth its weight in macaroons) and typically run out quickly. I am not sure how, as the location is a bit tricky, but regardless, whenever I go there are normally not that many left.
One time I bothered to get the fondue-to-go but I didn't get far because there were no lids for the chocolate, making it hard to transport beyond the door, and it was too tempting to not eat immediately. Messy, too.
The most indulgent part of the whole place is the decor - it's beautiful!
