People-watching and being seen is part of why the tony and tanned Psarou Beach dwellers flock to the open portico of Nammos, a Mykonos institution. Locals say you can get a better, cheaper meal at lunch than dinner, and pasta with sea urchins is a specialty. A gourmet dining room and a sushi restaurant are adjacent to the main restaurant, as is a beach club with a fitness room, spa and even hot yoga facilities.
