Hi Kerry,
It is a little while since I was in Calpe but I remember that La Regata stood out as a good restaurant. We also tried a chinese restaurant near the HR hotel which was ok. Also, had a snack meal on the terrace at Hotel Villa Marisol which was pleasant as they had a band playing that evening.
Moraira is nearby and there are several nice restaurants there, we especially liked the Greek restaurant and there's a lovely ice cream shop for dessert.
Further on in Denia there is a wide selection. Ticino on the harbour side is very good as are several of the others on the front.( El Port, El Raset ) On the Marques de Campo main street we had a nice meal in no.11. Along the marina there are numerous places , there is Zensa bar at the end with a rooftop pool where you can treat yourself to a cocktail and lie on the sofas enjoying the views. If you go in to Denia in the morning I can recommend going to the Valor Chocolate shop which sells the traditional breakfast of churros (hot strips of fried dough sprinkled with sugar ) and thick hot chocolate for dipping.
At El Vergel there is BB Restaurante which is a barbecue/ grill restaurant, It is excellent value. Further up the road is a new Wok Buffet ( not the one next to BB Restaurante ) at the Segaria Shopping Centre , there is a wide choice and again it is very reasonable.
If you really want to treat yourself try Casa Pepa at Ondara. We haven't eaten there , (could only stretch to a G and T on the terrace !) but it is highly regarded.
At Javea there are many restaurants along the beach front. We have had a couple of pleasant lunches at La Boheme which does reall tasty tapas We have also been to restaurants in the port area of Javea which do good ' menu del dia' deals at lunchtime.
I'm sure you'll find plenty of places to go. Have a good holiday and happy eating !
