I've been working here a lot (like a lot) this year due to the favorable atmosphere.
1. The space is ample, comfortable, and clean. There are some "rush" times with Google and other businesses nearby, but in general, this store has a nice, steady flow that never keeps you waiting too long or prohibits you from finding table or a spot to sit. Also, I dig the chairs and couch and the fireplace. All those huge wooden community tables at Starbucks stores are not comfortable. Plugs are plentiful. The store is usually spotlessly clean -- the staff is constantly cleaning -- as are the bathrooms. The coffee bar is aways fully stocked.
2. The staff is professional and helpful. I wouldn't go so far as to say friendly, but they do their jobs efficiently, and I've never seen an unhappy customer or a lazy or rude employee.
3. The coffee drinks are delicious. I've never had a bitter or burnt coffee. Also, they always have an enormous pitcher of ice water on the bar.
4. The food is good. Bonus points for the gluten-free: they carry Gluuteny products!
All in all, CTR-Bakery Square is a great option for a place to meet for coffee or to get some work done.
Just please don't take my chair--I like the one in the corner by the fireplace!
Only one thing makes me cringe: I wish this location would recycle--so much plastic and paper waste from the cups!
