I came here once this past Vegas trip, I was in town for work, but I have been numerous other times with my family when we would go to Vegas (2000-2004 or so) and it's always tasty.
I wanted something quick for breakfast so I got a croissant - they had regular or chocolate croissants - and an apple juice. It's definitely not an inexpensive place - it was about $8 for the two of those - but it has a nice sitting area and a good selection of breakfast stuff plus pastries.
