Great place, Great atmosphere.
Its person for people who've lived here forever, or for people who are visiting. Theres always something new. Its nice to just walk down along the pier or just walk into the old port to see the old shops and old streets. The restos are expensive, but thats normal for a very touristy area.
Make sure to check out the square right in the middle of the action. In the summer there are artists who do caricatures and so on.
In the winter, there are usually some great maple syrup stands (but its really expensive).
