Although you can say there is a difference between food in the North and South, it is more diverse than that. I actually read somewhere it is heavily influenced by the peppers grown in the region. Peppers are a very diverse species, and frequently cultivated locally. This means that a city might have dishes using sweet peppers, while the town next to it has hot peppers. Personally, the thing I like best is naan, and any bread. For me, some fresh bread and some garlic paste is the best.
