Ericeira is a seaside town, still within 'weekender' reach of Lisbon. The picture is of the main beach, with some people and their dogs. The bottom picture is of the same people and their dogs, after I have zoomed in on them with my little bridge camera.
At the back on that rocky point, is a parking area. Just over the top of that point and served by the parking area is the Esplanade Furnas, a great fish restaurant, where you pick your fish from the daily catch (don't worry they help you understanding the types of fish), you place your order by size and the waiter will then seat you. The chef will then barbeque your fish over coals. I really enjoyed that fish and can recommend the place. You can be seated right next to the sea, so to speak. http://www.restaurantefurnasericeira.com/#/destaques for a look if you have a moment.
