I went here for lunch on a Sunday. I'm single (sob! ;-)) but was in a group of couples with kids. Lots of buggies/strollers and toddlers to contend with. There was a queue to get in but it moved fairly rapidly. Once we got through the entrance, it was clear that this restaurant was perfect for our type of group. Staff were very helpful and multiple high chairs were sourced. The strollers were stored within minutes and adjoining tables found. The older kids headed straight for the happy chaos of the play area and we went about the adventure of finding some food.
Like the other reviewers have said, this is an open restaurant with multiple stalls to choose from. You get a swipe card on arrival and use it when ordering your food. There is lots of choice-all types of hot food, salads, pastries, sushi. It was Easter Sunday and the last day of my trip so I made a beeline for the crepe bar. Got a really yummy banana crepe with chocolate sauce and ice-cream. Yum! The other meals looked very tasty too and everyone seemed happy. It's not Michelin star material but it's good...
It is expensive for what you get...but it's also fun and especially good for groups because there is a choice for absolutely everybody. Would definitely go again-just wish it was a bit cheaper!
