In general this is a really nice restaurant with good interior design and high quality products that gives it best to fullfill "Western" expectations. Thus, it is a little bit more pricy than the rest of Bali, whereas you should know that this area in general is a little bit more expensive than the rest.
The food was good (cannot rememeber what we had), the portions a little bit small, the service friendly and professional. However, there is one thing I didn't like (but this is really a very personal perspective): Olive is a little bit too posh and chic and not relly my type of restaurants, as the personality is missing somehow.
All in all I can recommend coming here for one night.
