I've been to just about very highly rated burger place in London in the hope of finding something that compares to what you can get in the US and none of them come close. That's not to say they are horrible, I'll still happily eat them but they don't come close to some of the places I've been to in NY, Austin etc
Even at the lowest range of burgers the uk is worse.
Mcdonalds, Burger King both taste better than the UK versions and then thy have genuinely class low cost burger gains like in and out which wipe the floor with anything I've had over here.
Well, I'm never going to america.
Imagine having british burgers ruined for me for ever. I might lose 8 stone.
