I have been going to Cous Cous for a little over a year now. I work at one of the area businesses and had enjoyed having an occasional supper there. Tonight my expectations were high as I know their Lamb Shawarma plate is delicious! However, I was sorely disappointed. Not only was the staff lacking in personality and pleasantness, but the food was terrible. When I finally received my plate, (the service was stunningly slow) the meat was incredibly over done. The lamb was tough, chewy and lacked any flavor. The offered to redo the plate or cook a lamb kabob for me, but I could not get the terrible taste of the over done meat from my mouth. I declined and requested my money back. With that, it appeared they did not want to do the refund. I thought I would need to get a bit firm with them, but then they must have finished the debate within themselves and chose to do the refund after all. Needless to say, I will not go back. I know I had several good suppers with them before, but that was seriously enough to deter me from eating there again.
