We had a horrible experience in Ruatabaga on 09/09/2015. I don't even know where to start from - the slow service, the bad attitude or the horrible food. Our reservation was for 8.30pm and the food only started arriving at 10:40pm. Half of the dishes on the menu weren't avaible and there was no vegetarian option anymore. I ordered a roasted vegetables salad which was 14 € on the menu and the chef proposed to make make it an evening dish. At the end I received a small salad with a few green leaves soaked in vinegar and salt with a few pieces of cooked butternut squash (no sign of any other roasted vegetables..). I couldn't even eat half of it because of all the vinegar and salt. At the end when the billed arrived my slad was billed as main dish with fish for 22 € without anyone explaining this is actually the salad. When I went to ask the chef about it she just started yelling at us for questioning her pricing. 
I must say that the rest of the group enjoyed their food, only the salad was a big failure. Very overpriced for what it is. 
The atmosphere is nice, however the table we had was in a corner, completely isolated and next to the big fridge.. so we couldn't event enjoy the nice atmosphere in the restaurant. It was a waste of money and time.
