text: In a time when Las Vegas restaurants are remodeling left and right in order to provide a more causal dining experience, Sage still has an almost hidden entryway.  We stopped by near opening time for cocktails ... and a little foie gras.  Originally skeptical, the Foie Gras Custard Brulee was enough to make us want to stop by for a full dinner sometime.\n\nThe bar has some good beer on tap - mostly Belgians or Belgian-styles.  They also have a respectable classic cocktail menu.  We came to try out some absinthe, though.  They're a little ... overly sensationalistic ... about the recent availability and changes in law, but they have a decent selection of bottles to choose from and are happy to make recommendations in a variety of price ranges.  They also do the fun, flaming \"Bohemian Method\" of serving it ... or the more staid French water dripping thing.\n\nService at the bar was friendly and fun ... we were about the only people in the restaurant at that hour, though.
