Hence I cannot provide a primer on the best sushi in Cairo. But my friend Mona Daoud, loves sushi and this is her list of recommendations for sushi in Cairo.
Jo Sushi on Mohamed Mazhar street in Zamalek has it's on days and off days. Depends on your luck... just make sure to tell them not to use wasabi while preparing sushi for you because they mistakenly think that if they're generous with it, it will taste better.
There's also INakaYa , 6A Midan Aswan in Mohandessin. They have all you can eat nights for 90 LE on Saturday, Monday and Wednesday. I haven't tried them though, so I'm not sure if they're good. I only heard about them.
