We went to 'Le Bon Vivre' with Narelle's conversation group last night. Right on place Wilson, it's of the fancier sort: fabric table cloth and serviettes and all. The service is nice though strangely amateurish for a place like that (I get prejudiced based on the serviettes). First price menu for dinner is 22EUR, we ended at about 40EUR a head after wines and coffees were added.
The food is very French and all very nice, although the cassoulet does not beat Le canard sur le toit in Tournefeuille.
It's not non-smoking, but the waiter assured us that very few people smoked. We had bad experience with this sort of judgement before, but in this case it was true: probably about 3 cigarettes were smoked over the evening, that is, from 7pm to 10pm: perfectly bearable.
