You're all SO wrong about TK Maxx in London being better than the rest of the country. I live in London and I'm surrounded by shite TK Maxx shops! The best ones I've been to are the Brighton one and the Cambridge one.
Does anyone know which of the London ones is biggest? I need one that does homewares (particularly bedlinen and stuff). All the ones I've tried (Leyton, Wood Green, Brent X) just do clothes.
