Lived there for a while many years ago and finally going back for another extended stay. Times I was there briefly in recent years, have been continually shocked by how much and how quickly things keep changing!
Looking for places along the lines of these:
Les Grandes Marches -- always seems busy and convivial
Hotel Costes -- love the atmosphere
Buddha Bar -- getting a bit tired of it...
Au Pied de Cochon -- classic for 24/7 brasserie
Am mid-30's and single, so I do like a place with a similar crowd into their 40's. And an attractive atmosphere and great food!!
