There are three Starbucks Cafe in Luxor Hotel, the one on the main floor closing by the Hotel reception open all the time when ever we are passing by, I have no complain about the cafe price even you have pay a bit more ( $3 for a regular one ) $ 1 for hot Water, but for water bottle it cost $ 7 /L is way...way out of hand specially you have to drink a lot on the hot day :( ! We crossed the walk way to ABC ( North from MGM ) and pay $ 1 / L.! The money saving for few bottles of water would buy you a decent lunch !
