Broomhill punches above its size: CAWA hand-roasts on-site, and Nam Song is one of the few places in the UK doing phin-filter Vietnamese coffee properly.
Worth going out of your way
Sheffield's home of the phin filter, built entirely around Asian coffee origins. Order the Cà Phê Trứng (egg coffee) or Cà Phê Muối (salt coffee) and you'll understand why this place has its own dedicated following.
A micro-roastery tucked inside a neighbourhood bakery-café: CAWA hand-roasts its own beans in Sheffield and pours V60 single origins with proper tasting notes, quietly doing specialty coffee while everyone else orders the cinnamon buns.
