Hiring a driver is affordable. Save all the trouble if going with a family. Most of them are nice and use a 7-seater. Can PM me if you want the contact of the driver we hired last time.
For nice food,
Ibu Oka Babi Guling
Naughty Nuri BBQ Ribs
Dirty Ducks
Mt. Batur for the volcano view, normally come with buffet lunch where you eat and look at the scene, food are ok.
Jimbaran beach for sunset and seafood, the seafood are so so, we end up enjoying the BBQ corn sold from stalls at the beach more.
If family include kids, can go to the turtle island from Nusa Dua for photo with turtles, lizards, bat, hawks and other animals.
