I've been a customer here for a few years now. My overall impression is that this is an unpretentious place that doesn't try to cater to any particular type of customer. It is nice to hear classical music often played over the sound system.
Baristas have been consistently polite and/or friendly. Baristas do not play watch over what people are or are not doing. A good place to study or have a quiet conversation.
The coffee is decent, not as caffeine-rich as Starbucks's, I haven't had any coffee problems after something close to 100 orders.
