It is a very nice wine shop and restaurant. We were able to eat gluten-free without problems, the owner told us what we could eat and what we couldn't. My wife has celiac disease and I don't know if she contaminated anything. Highly recommended for celiacs, since in France it is not easy to find good places and with empathy for celiacs.
The beef tartare is highly recommended, with a very generous quantity.
I would return without hesitation.
