Let's get this straight once and forever: there are TWO "M Sayhoun" falafel shops. Both are in Damascus Street, both are run by brothers and they are next door to one another. The left hand shop is run by Fuad Sayhoun, the right by Zouheir. The brothers were both trained in the dark and delicate art of creating the perfect falafel sandwich by their father, Mustapha, whose name adorns both brothers' shopfronts. Mustapha founded the business in 1933.

But, here's the catch, the reason there are two shops is that the brothers fell out, irreconcilably, and they never talk or socialise. To describe their relationship as one of hatred is about right.

Zouheir makes excellent falafel. It is tasty, cheap, filling and so good it will make you want another. Don't, just go back another day. The simplicity of the sandwich is its secret - three little balls of fried chickpea taken from the ring of them warming on the rim of the fryer, mixed with some parsley, radish, tomato and tarator, a tahini sauce, all wrapped in thin pita bread.

Zouheir charges 3,000LL, about $2, for a sandwich, amazing value. Cold drinks are sold from a little cooler behind the counter. There are a couple of stools, normally occupied by regulars, so hang outside and enjoy.

Highly recommended.
