Don't laugh, Galaxy Chinese Restaurant Mombasa is one of the best Chinese restaurants I have ever been to in my life. I regularly go there when I'm in Mombasa.
It's located on the island, run by a real Chinese family and serves amazing food. It is based on Hainanese recipes, which are my favourite.
You must try the fish in garlic sauce, sticky ribs, fried rice, whole steamed fresh fish and black pepper crab. Brilliant.
Excellent freshly prepared food, great service, nice atmosphere.
China has several provinces and the cuisine varies in each province. For someone to say that the food in China is different, simply doesn't know what he/she is talking about. Even a Chinese person will tell you that.
They also have a branch in the South Coast, Diani. Do not go there, I think it is of a lower quality. Go to the one in Mombasa town. It is a must.
