I tend to stick to local coffee shops, but Starbucks on fifth has won me over with their customer service. The workers know my name and drink. Try a double shot on ice with white mocha-- thee best!
The drive-thru people are nice enough but if you walk-in and you're not a senior citizen, there's a fair chance you'll be rewarded with a monotone and some eye rolls.
I think when I left my first tip I was bitter about my leaving my familiar Starbucks where I used to live. This one isn't the same but I've warmed up to it. They're not so scowly after all.
