Ate here every day if not 2x a day while here for my week stay. My findings:
Super convenient if staying at the jubilee tower. Right at the base of the elevator.
Food seems fresh! Nice case of ready to go fruit trays, cookies, pastries. I was incredibly impressed with the cheese plate, exotic cheeses with fresh and dried fruit, garlic, capers. Awesome snack for $6.
Be warned, every morning the line is outrageous. It apparently is the only breakfast spot apart from the coffee/snack kiosk by checkin desk. The line gets LONG. And you WILL inevitably get behind one (if not two, depending on your vegas luck for the day) foreign families who have absolutely NO idea what is going on.
Their salmon lox bagel sandwhich is delicious though and the staff I encountered was very friendly.
