Like the couch-cushion fortresses of youth, men-only barber shops provide an unassailable barrier that not even the most contagious of cootie carriers can penetrate. Remodel your he-façade from the safety of a man castle with today's Groupon: for $20, you get a haircut and straight-razor shave at Johnny D's Barber Shop, a $45 value.

Modeled on the shops that once filled the land in the years when barber was still short for barbarian, Johnny D's is among the last men standing in the haircut world. Frills are purposefully kept to a minumum, but the services are honest, direct, and solid. The hair chop shop features cuts that leave clients dashing and close cropped just in time for blast-off in a Saturn V rocket, while the hot, lathery shave leaves faces smoother than the freshly waxed cherry-red fins on a '57 Cadillac. Each cut is tailored to match the demands of the hair bearer seated in one of the comfy chairs.

Made for conversation, grumbling, and generally killing time, Johnny's fosters an atmosphere where men can be men, even cry a while if need be. Fully grown guys and youthful dudes with full heads of hair are welcome to grab a seat and talk it up with a well-trained barber as he snips unruly locks into submission.

Like all manly business, Johnny D's is closed Sunday and Monday.
