MTDC Ganpatipule is one of the best sea side resorts which are well maintained and serve good food. The mandir is very close to the resorts, and the beach is almost like a private beach with restaurant also on the beach where u can order veg, non-veg and drinks too. If you really like beach then I will suggest go for Konkani hut. Also if you are really tate conscious go for a restaurant "Sameer" located near the mandir which serves delicious fish food.
Also try to do a complete pradakshina of mandir which is almost 1/2 a KM. An ideal stay for 2-3days with friends and family....! dont miss this one!
