Found this place via Trip Advisor and, after being ripped off in the main square, needed a decent meal and Oscar Progres didn't disappoint. Had the 100 dirham four-course, fixed menu, morrocan salad to start which was lovely, wife had chicken brochettes next and I had lamb cutlets, both great, and we both had chicken tajin which was delicious and a really good size.
The place was simple and unpretentious with plain decor and it was nice and quiet after the madness of the main square. Clientele included locals and tourists which is always promising. I'd definitely go again.
