Yes in short you can but you need to be selective. Many high-carb drinks are of the drinks menu (such as some cocktails, sweet wines, and many beers, for example.), Concentrate on drinking pure liquor or dry wines, you can definitely enjoy a glass or two of these. Some cocktails are great also such as this amazing martini.
Lots of keto dieters comment that get drunk much faster than they are used to on keto, so bear that in mind, and go slower than usual. Not only that alcohol has lots of calories and so body needs to burn these calories prior to everything else. The good news though is that alcoholic beverages are more than possible on keto.
