I have been to both Starbucks and Costa Coffee. They have their good and bad stuff.
Mugs and Tumblers and ****: Starbucks, all the way.
Coffee: Undecided. They both suck when it comes to coffee.
Atmosphere: Starbucks. Costa is not that far behind.
Ham & Cheese Paninis: Costa hands down.
I would choose Costa by a hair.

Gloria Jeans?

the one and only Starbucks

I'm from Jersey so none. Dunkin Donuts all the way

Costa>>>>

We don't have costa here

but my favorite is"Coffee Bean & Tea Leaf"

but out of those choices, starbucks

Costa.

Tim Hortons. There's one on practically every intersection in Canada. It's hard to find Starbucks here and that's a good thing because I hate it.
