I've also eaten Taco Bell.
You're not missing much. It is much as you'd expect, a stepped-on Americanised parody of Mexican food. Even in the small north-eastern city of 150,000 people I live near now there are at least three places better than it for Mexican food.
Starbucks is absolutely rank. I suspect all the syrups and shit people pump in is just there because they a) don't actually like coffee and want some sugary milkshake, and b) don't know what coffee tastes like so are okay with the stale over-roasted to the point of just being burnt lukewarm rubbish that Starbucks sells.
The rest of those don't really exist in the UK (yet!). I don't know if "Generic Brewery" is a real place or just a term for "oh hey you have to check <this place>" out, but if it's the latter then that would be Brewdog. Okay but not great beer, horrible horrible people.
I used to work at a small workshop in the south side of Glasgow where I'd go out and get a curry for lunch most days. The building looked semi-derelict but the shop itself was clean enough. Stainless counter, stainless kitchen units behind where two big Pakistani guys and their tiny grandmother who *everyone* deferred to cooked up curry. Cracked lino, scuffed formica tables.
You went in, you bought curry and a can of Coke. What kind of curry? Whatever they'd made that day. There was one, or maybe two if they also had a veg-only one on. It was whatever Naniamma had told them to make that day. Your menu choice was buy the curry or don't. Doesn't matter either way. Four quid please, want a fork?
It was always superb, and 20 years later I can still taste it just thinking about it. This is the kind of place you could eat.
