Went to the Red Sun twice whilst working in Marrakech. The restaurant is located at the side of Pasha nightclub and is about 2 miles out of the town centre.
First impressions were good, the place looks and feels quite upmarket.
The menu is varied in that it offers Moroccan food, as well as Chinese, Thai and Japanese dishes. Prices are good.
On the first visit I tried the chicken in sweet chilli sauce with cashew nuts which was tasty and on the last visit I went for the chicken in teriyaki sauce, which again was very nice.
