mcdonalds is absolutely disgusting, tastes of chemicals and sugar, not even slightly beefy, nasty.
In a cheeseburger in mcdonalds if you take the gherkins out, it is technically classed as a pudding.
It might be because i eat very little proccesed food but i can taste the chemicals and they actually make me feel sick after eating a mcdonalds, heachey and just want to throw. If you have a chemical filled diet it might be different, i don't know.
Burger king is slightly better, but not by much, the burgers are of a decent size in bk at least.
Wimpy is good, the burgers are actually alright and taste like beef but theres only a few left.
I don't tend to eat from chains anyway though, apart from kfc, if only the chicken was of a decent quality i'd eat there every day.
Oh and subway, good value for money, meatball marinara foot long makes a good snack, for 4 quid on tuesdays, bargain.
