Sure I won't be rate popular after this, but I couldn't imagine anything worse than eating a full english. Yuuuk
The one on the lay-by near Tankersley golf course used to be brilliant. Not been for a few years though. It used to be open 24/7, was a good place for late night scran. Only day it used to shut was Christmas Day.
Nothing better on an away day in London than an Irish breakfast at O'Neill's outside kings cross. It comes with white pudding!
Used to live round the corner opposite Spitalfield market and then later worked at the RBS Buildings near by. Have had many a hungover fry up in there. There used to be a good fry up at a place called S&M cafe near by but its a vietnamese now. Had a decent breakfast pre pandemic at the Major of Scaredycat town which is also nearby. If you know the password, theres a secret cocktail bar accessed by going into the american fridge.
