Open Letter to Him: You’ve come a long way, baby. (Not so long ago, you were toting a rifle and wearing coonskin.) But don’t be fooled: A dab of hair gel and a tucked-in shirt do not a metrosexual make. Guise, the new one-stop shop and spa for men, can help take you to the next level. Step up to the stainless-steel bar flanked by giant TVs and have a manicure (!?) while nursing (!?) a complimentary (!?) beer. Need a haircut, but only have time when the Illini are on? No need to miss a minute of the action: Each styling station is equipped with a mini flat-screen and a pair of headphones. Once you’ve had your fill of spa services (everything from barbershop-style shaves to shoe shines), check out Guise’s clothing offerings, which include selections from designers like Yanuk, James Perse, Theory, Nicole Farhi, and Jack Spade. Finally, you can look good without sacrificing an ounce of masculinity. Though you may have to lose the five-year-old tighty-whities. Love ya lots, Her Guise, 2217 North Halsted Street, Between Webster and Belden Avenues (773-929-6101).
