Try the littel fishing harbours on the north coast, Rozel, Bouley Bay, Bonne Nuit, and Greve de Lecq. Park at St Lawrence Church and explore the lanes behind the church to find the real Jersey. Also, St Martin's Church, St Catherines. The west coast is amazing with sand dunes that go down to the sea. Lots to explore along that coast - L'Etacq, and Les Landes, and Grosnez. Restaurants I would recommend are Mark Jordan at the Beach for fab sea food, the Beach Club at St Brelade's Bay, Gorey just below the castle also has some lovely restaurants like The Moorings. St Aubin's is well worth a walk around and perhaps a lunch at the Somerville Hotel. May is by far the best time to visit as all the spring flowers and trees are out and it is not so busy. Have fun!
