The restaurant you went is not that expensive just mid range.

If you want expensive go to Sakala, Warong Alila or Mozaic min person would 1mil rupiah

Nah those places you went are touristy and expensive

There is better cheaper local food than those places like Naughty Nuri's now full of tourist. I been there years back when it was still cheap as the ribs were half the current price now.

Tell your cousin go try those places i quoted earlier as those creme de la creme of Bali restaurants.
