Disappointing food

I bought a gourmet burger and cheesy steak nachos at flambos in Parow on Friday. The chips that came with the burger was cold, the gourmet burger had plastic in between the patty and the garnish. The steak of the nachos was salty. I called the manager to inform him and he was not apologetic at all. The entrance of the restaurant was filthy with papers lying on the floor, and the couch in the waiting area was sticky. I will never order food there again.
