I stay at the Monte Carlo quite often and it's always been McDonald or SBux at the food court in the morning for me. Sambalatte is definitely a nice option to have in the new outdoor area of MC.
A gourmet cafe, Sambalatte serves up espresso drinks and single origin, via pour or vacuum. Got to watch the barista make the vacuum coffee several times. It does take awhile and it is best to ask baristas on the single origin they have for the day. My go-to here is the iced latte. Espresso here is great and love the milk they use here. Milk is very milky but the flavors of the espresso still comes through.
There's also some food items, but selection's not too big. Ham & cheese croissant is great and the chocolate croissant is tasty when warmed up. I do find myself getting food at McD after getting a drink here though.
Price is definitely on the pricey side. A large iced latte and a ham&cheese croissant is over $14. Was pretty shocked, but it's to be expected. What's not overpriced in Vegas, especially on the Strip?
