Since this turned into a "Best CHEAP Places to eat in T&T" thread, I'll add:
Yifu Garden - St. James - There are some specials at the end of their menu that come with special fried rice. Good Stuff.
Arabic - Arabian Nights - Highland Plaza, Glencoe or the Gyro Cart in St. James most nights, or Lawrence of Arabia - Long Circular Mall. (Can't believe how many people actually like Lawrence of Arabia, Maraval's food

)
Mangoes on the Avenue is good for variety when looking for lunch.
If it hadn't turned into a "cheap" thread I would have asked how come Zanzibar wasn't listed by anyone?
Come to think of it Mongolian Grill, Trincity is very good too.
BTW, I'd never buy food (again) at a place that has as many flies as the Highway Roti Shop place. It's disgusting.
