I've been here a couple of times to hunker down and study. As is with many other joints of this calibre, there is plenty of room for improvement.
The staff, it seems, are content with their job. A few of them are immigrants who comprehend and speak English fluently, but will understandably not get everything. If you order a decaf, for instance, you might just get a regular. That said, our cashier seemed to be borderline disrespectful and unprofessional for his job. He might have been aiming for a friendly and nonchalant approach, but it could come off as the opposite.
The intent of the setting is to instigate a cozy atmosphere. With the faux stone flooring, juxtaposed by the dingy LED fireplace and bits of litter all over the ground, it's definitely a nice attempt.
