As someone who's constantly concerns about the cleanliness of juice bars, La Fraise will always be my first choice. The only downside is how inconsistent they can be. Banana Toffee is my favourite.
This place is legendary! Well priced (Average Juice around 10 LE) . I strongly recommmend it for anyone who's thirsty and has a sweet tooth! ;) Don't forget to try out the Salade des Fruits
