Coffee Appreciation

When I'm left in the terrible predicament of only having access to a Nero, Costa, or Starbucks (like at a train station or something), I always go for Nero for some odd reason. I refuse to go into Starbucks, just hate everything about it, and the last espresso I had there certainly didn't taste like coffee.

Do people reckon Costa is the superior of the three?

I always found that Costa did all the prep well: cup warmed, pour timed well, decent (ish) looking creama etc but their beans just didn't taste of anything. Bland as fuck, hemce I always though that Nero was better as their beans at least had a generic coffee taste.
