If you've been to more than one Starbucks, you know they're all pretty much the same. Thus, it's the small things that differentiate them.
This one happens to have lots of space, a bar off to the side (so people waiting in line aren't bumping their butts/bags into people enjoying their drinks) and friendly staff.
As someone who was there to relax with a book, I was pleased by the relatively low noise level considering the large crowd (the only person I could hear was an obnoxious-as-hell wedding planner giving awful advice to a bride-to-be).
However, there are only a few comfortable chairs -- it's clearly set up for meetings and individuals looking to plug in their laptops, not relaxers.
High ceilings, reliably OK drinks, good location = 4 stars amongst the world's Starbuckses (ha!), surely.
