Marmara istanbul on Fereej bin Nasser is the best branch of their's and I've always enjoyed the food there; this branch in bin omran has always struggled with these violations, don't know why the difference in standards...but yes, ever since I tried "Lebanese Shawarma" on Matar Qadeem St., I've just not gone to any of my old favourites; I've grown up here and tried almost every shawarma place but this one I mentioned is just another level of awesomeness for me at least...their beef shawarma is one of the best in Qatar and I can't stop stuffing my face with rocket after rocket haha...
