i pretty much feel the same. i neither love nor hate maccas, i dislike the concept of all chain fast food basically, but i'm not above going to the one close to my house if i just don't have anything at home, which rarely happens anyway. i don't even think it's that bad, pretty much all fast food is unhealthy, they all fucking suck. mc donalds actually tastes consistently decent tho. but it's never really good. i guess the main highlight of a german mc donalds is that mcribs are available all the time and i heard it's generally pretty good compared to other countries. i had it in the netherlands, czechia and france, and to me it tasted all the same.
now five guys also came to germany and i went there and was pretty disappointed, especially the fries. my fries were soggy as fuck, like they skipped the second fry. they put an extra bunch of fries into the doggybag, as they do, i appreciated that effort for sure. but they just weren't done imo. the burger was ok, but basically tasted like a slightly better mcdonalds cheeseburger. i would say it was like that, but way bigger and with slightly fresher ingredients. and that burger was more than ten bucks. and if you forced me at gunpoint to spend ten bucks on cheeseburgers, i'm sorry to say that i will rather take three mc doublecheeseburgers over a single five guys doublepatty cheeser. it's just not that much better. but i might as well buy a pack of marlboro reds instead and just not eat.
nowadays burgers usually make me feel sick, even if they were very good. just hard to stomach and often goes along with too much soda consumption. i'm not a big fan of them anymore and have become too lazy and unexcited about them to cook any at home anymore.
