Coffee Appreciation

Quick poll of the three major franchised coffee stores, who makes the best coffee?

Starbucks?
Costa?
Nero?

Doubt anyone on here has been to the three of those ^ recently to give you a fair appraisal.

I had a macchiato from a Costa franchise in a Tesco's last week. I knew it would be shit (and I could of had a tea to stave off the headaches) but thought lets see..............it was shit.
