The best is Papa Johns, Go for the value meal they have... its superb. especially their cheese sticks..

Sbarro.... Its the worst in Doha.... I ever tried. yuk... ready made junks.. I dont know how people enjoy the food there... I went there with my family and that was the first time I ever left a restaurant without eating what I ordered . And I paid for it though.

And hey for another try .. go fo CHIAO in AL Khor. Its great
