Wow, the self serve kiosks are very interesting. You can pay in plastic at the kiosk or pay in cash at the counter (only 1 register) No that there are no more cashiers there are a few people roaming the restaurant greeting people to use the kiosks and offer refills and other services for customers.
Staff was nice and friendly.
With the kiosks however, I found it quite difficult to modify drinks. I like having my iced coffee with milk instead of cream for instance.
