LaPlaya on Orient beach has been advertising parties in the evenings and Yellow Submarine is the restaurant/bar in the village that is open at night. There are probably other beach bars open at night as long as there is a crowd otherwise except for dinner the area is fairly quiet once you get into the later evening hours.

Additionally there is a small bar with a few outdoors tables serving food (near Petit Casino (sp?)) that is open late. It has changed hands a few times in the last several years but seems to keep to the same format of light food and drink.
