Is there a dress code at any of the restaurants, like Coco Bistro or any of the other upscale restaurants (e.g., no sandals for men)? I made a reservation at Coco Bistro and planned to wing the rest of the trip so we aren't on a schedule. Do other restaurants require or have a long wait (longer than an hour) to get a table (e.g., Le Bouchon)?
Also nightlife, do things shut down relatively early? Where are some good places to grab a late night drink with local bands?
