When I come here, it's usually for lunch. It gets crowded pretty fast during the week day. While I know some people who swear by their coffee, I'm just OK with it.
You can get seated first, however, then you have to get up again to order and pay for your order yourself at the counter. The food and drinks will be brought over to you. There's an automatic 12% service charge even before anything is served which I doubt really appreciate. What if the food was awful or if we didn't get service? There wouldn't be any incentive to perform well as we would have already paid. Students get 20% off.
The lunch specials are mostly sandwiches which are very tasty and are usually served alongside olives and peppers. The last time I went I had a grilled chicken sandwich which was quite nice.
