Northern Tea Power.
If it is possible, Manchester gets cooler and more coffee (and burger) based by the day. Northern Tea Power feels particularly Manchester - it has a cement wielding edge over its more sugary 'twee' counter parts.
I spent an afternoon sat dry and smug watching passers by wrestle with unruly umbrellas through the rain. I'm not sure why I am ever shocked that Manchester is raining but I still haven't developed a permanent bubble to protect me from it just yet.
I would recommend the latte, grilled cheese sandwiches and also possibly the branding as that is pretty badass. Go forth and devour.
