Service is terrific, ambiance is very brasserie, i's are dotted, t's are crossed with Thomas Keller frequenting this restaurant. The roast chicken was moist, the waffles crunchy and fluffy at the same time.   Moules mariniere were simple but delicious and sauce was eagerly mopped up with crusty baguettes. And yes.  His frites are 100% better than at Les Halles. We ate here 3 times in out 7 day stay in Vegas.
