the selection o food menus in all resorts are fairly much the same but Caluwayan's is more upmarket meaning cooked by a cook/chef! Choices are the usual served by most restaurants in the country - basic filipino and continental dishes
there are buses though infrequent but a lot of vans go by the hour to Borongan or Guiuan passing by Marabut. Make sure though that the trip "is via Marabut" as there are those that go to Borongan or Guiuan "via Buray-Taft". Duptours and VanVan's are the most reliable van companies that ply the route.
