Every time I venture out to some other chain, always end up coming back to Starbucks. It's very hard to beat the rewards, convenience, app, ambiance (for the price), and refills (a huge deal for anyone accustomed to doing work in a café for any length of time!)
What I really don't get is how people have coffee in donut places. Horrible watered down slop at Dunkin Donuts, Tim Hortons, etc. with a fast food vibe
