Been there once. Not bad but I think Del Frisco's has nicer ambiance. My impression of Stogies and Bogies was that it's marketing to the 30 to 40 year old demo. Being an old fart I find Del Frisco a bit more sedate and more to my liking.
You're limited in choices. Those are the only cigar bars that I know of in the south end of town. Actually there's own more, Devons Pub off I-25 and Hampden. Kinda of a local pub. Not fancy but friendly folk.
Other than that there's Churchill's in the Brown Palace in downtown Denver
