Nitida Cassia let's itself down

I have just been to Nitida Cassia restaurant for lunch with a friend from the UK and this is the first time I have been disappointed in the meal. The Cape Salmon was white and not pink, it was overcooked and extremely salty. Our friend didn't want the chips with her beefburger and asked if she could have vegetables instead and the waiter said that it wasn't possible as they couldn't serve a side of vegetables but she could have salad, which she declined. My partner and our guest asked for a Fortado and imagine their surprise when it was served in an espresso cup which gave them one mouthful of coffee! I have never seen a Fortado that wasn't served in a normal cup. We could and should of complained there and then but we didn't want to make a fuss in front of our visitor given that we had recommended the restaurant to her. Having had such an experience (and one that wasn't cheap) we will not be returning which is a pity as the setting is so good.
