Stogies Cigar Lounge in Sioux Falls, SD best atmosphere, gets a little crowded but if you get there at a good time you get some nice leather couches near a slick fireplace. Good music and good drinks, cigar selection is limited but good.

Outlaw Cigar in Kansas City, MO, best parties, huge humidor, free food (during a monthly event) and some decent guys to hang with.
