If you're in the very center (Leicester Sq, Picadilly Circus, Soho, et) and are looking for an affordable meal, this is a cool little restaurant specialized in Hummus dishes.
All hummus dishes are served with a warm pita bread and are best shared with some friends (chickpeas, guacamole, fava beans, chicken ... are some of the things you can add to your delicious hummus). A cool thing to try is their Aloe Vera juice, with a hint of honney and grape.
