Go earlier than you need to be! There is a security crossing to get into the restaurant. This caused us to be a little bit late but the staff is so friendly they don't worry about it (and it probably happens all the time because people don't expect it).
Service is good. The whole restaurant seems to move at it's own pace. It's a little slow - the time between people checking on your table, the wait for drinks, time between order and food arrival - but it's not terrible, it is what it is and it seems to fit the slow rotation of the restaurant.
The food was great. Not incredible hence not 5 stars. My duck was meh... was better with the sauce intended for the beef. But the steak was amazing... melt in your mouth greatness. The free-range chicken was delicious as well, a tad too much cheese inside but the taste more than made up for it.
Totally recommend going.
