Muslims and the fast food industry is not usually a good mix esp. when one lives in some of these countries. I know many of us dont hesitate to order burgers and whatnot from Mcdonalds and such but how sure are u that food is actually halal. Why take the risk and wing it. And later get shocked when u find that ur dua has not been accepted.

R u fulfilling the conditions for ur dua,saum and salat to be accepted by Allah? Surely,we shouldnt fast All day only to break our saum with food that u r not sure is lawful for u to consume.

On the authority of Abu Hurairah, who said : the messenger of Allah said :
[the case of] a man who, having journeyed far, is dishevelled and dusty and who spreads out his hands to the sky) [saying] : "O Lord! O Lord!" - while his food is unlawful, his drink unlawful, his clothing unlawful, and he is nourished unlawfully, so how can he be answered !"
