KGB probably has the best selection of burgers that I have seen in all my trips to Vegas, there's something for everyone. The portions are large and they take it all seriously, everything seems to made from scratch and cooked to order.
The decor of the place is a cartoonish theme of old Soviet propaganda posters which is a fun experience that gives the place a nice atmosphere. The drink list has some of their own drinks on it and they go along nicely with the food they serve.
