I was reluctant to use a gifted Groupon for Nyala due to previous comments however we were delighted with this restaurant.  The service was friendly and timely.  The meals were wonderful, the lamb tagine was extremely tasty and the spicy prawns were in a delicious sauce with peppers and tomatoes.  Accompanied by freshly cooked rice and a specialty bread, don't know the name but it was perfect for dipping in the amazing sauces.
We were given (on the house) some light and refreshing tabouleh salad with brown lentils also very nice.
Perhaps the prices seems a little high but there is no extra charge for accompaniments.  I would definitely like to return as we were pleasantly surprised.  Sorry no room for dessert as the portions were good.  Thank you Nyala Restaurant for a very memorable meal.
