Time to kick the tires on your liver. Cinco de Mayo is right around the corner. Not to be confused with Mexican Independence Day (September 15-16) Cinco de Mayo commemorates Mexico’s defeat of the French in 1862. And with so many dining, party and drinking options, don’t even think about letting “Cinco de Drink-o” go by uncelebrated. Las Vegas has some plans for you, my friend. And after a few tequila shots, well, you know how she gets.
