mate i managed a coffee shop for a year, i took numerous tests and have won awards. i very much doubt that.
its got a nice vibe in there but their coffee isnt that good, i got a latte from there and it was probably about 140 degrees, too cold.
Costa is wack though, they've got about 5 different drinks and use 1 espresso bean. My shop had about 30 drinks and 23 different beans.
starbucks use automated machines for their milk so its the same temp everytime unless you ask for extra hot. i've had some horrible cups of coffee in england, they dont train their staff well enough in general. starbucks is probably the only company in the uk where the barista actually knows anything about the coffee, pity their beans taste like crap. not sure if they do drip coffee in the starbucks in the uk but in canada is the worst drip coffee ive ever tasted, absolute vile, took 2 sips and chucked it away.
I went to Costa yesterday but I cant stand the stench of coffee beans in coffee shops it gives me a headache
