I didn't expect much from this in-hotel Market Cafe and did not particularly want to eat breakfast here since Vegas has so many food options. Buuuut, when you're hangry you're hangry so we dined in for breakfast the morning after we arrived. My husband and I shared the smoked salmon toastie and the breakfast bowl both of which were very tasty and filling. Everything on the menu feels especially expensive compared to non-vegas pricing but I felt like the portions and quality of food justify the pricing. At least you're not paying $14 for a crappy continental breakfast through room service.
We came back for breakfast again and got the power bowl and breakfast burger. Again, food was tasty, presentation was good, and we were happy.
If you are staying at Vdara this is a good breakfast option.
