If there's one thing I cannot thole it's sub-standard coffee.
The worst of the lot is that milky vomit they serve up in 'builder' cafes.
Starbucks are a fraud - rarely have I had a decent coffee from them, and they their 'fair-trade' policy is dubious.
The best of the high street coffee bars IMO is Cafe Nero: good quality, decent strength, forgeable loyalty cards - it's genius siting a couple of their branches for the tired traveller in Heathrow and Gatwick.
My setup here at home is: Gaggia espresso machine (permanently set up with the 'double' espresso holder), microwave to warm the milk, and Taylors Hot Lava Java - strength 6 :-)
So - back to my question, are you a coffee connoisseur, do you have a decent set-up or do you just bung a spoonfull of Maxwell house into a mug, slop water onto it and glug?
