Yup, Starbuck's sucks. Even if it were priced reasonably or free - it's not good enough to drink. Blech. And no one can say I haven't given it a fair chance either, I've tried it many a time.
Timmy's still wins for me in the cheap, reliable, and easy to please everybody range.
Their coffee isn't my favorite, but it's not bad at all.
I agree with Mame that Seattle's Best is a decent cup of joe. I prefer being able to brew it ourselves though - as I don't like my coffee too strong (and for the simple fact that way too many places let their coffee sit way too long!) and I like to drink it black.
McD's coffee too isn't bad now, but they are bad for letting their coffee sit and people not putting any 'love' into the process.
For the real treat of going out for coffee, I tend to hit up the littler shops that don't necessarily specialize in coffee. The thing to look for is an owner/manager who really cares and has a passion for coffee!
Sounds cheesy but it's true...better coffee when it's bought and brewed with love.
