We went there for breakfast. It was a semi long wait to get in on a weekday (abt 30 mins). The waiter we had didn't refill drinks at all so wasn't impressed with the service.
But as for the thing that matters, the food was pretty good. The omelette station, crepe station and others were pretty good. One disappointing thing is that I didn't see any cheeses and baguettes. I think they were out or something or we arrived a little late.
This was the best breakfast buffet of the ones we tried when it comes to food quality, but the wait and the service isn't.
