Egoiste is nice place to spend sunny day on their sun beds. But notice that there is the minimum order of 50 000 IDR while being there. They might come and ask if you gonna order anything or go away. Sometimes might feels a little bit unfriendly. Food is mainly ok, and chicken pesto pasta is excellent choice. Also carbonara is great. Service might vary a lot, as there is personnel changing. Clearly they have some things to be improved, not the professional personnel. You might have to wait your food a long time, even some Coke or other drink might take time (even they are on the fridge next to the desk).
The owner is French. On Trawangan this is very popular place, so just try it and you know, if it is good for you. We liked the place many times, but sometimes just the service level is not so good.
