There are times when you just want to feel special. You know, throw on those heels you saved up for and have nowhere to wear, get your hair and nails done, and — who knows? — maybe even shave your legs. Now, VIP Fridays, starting at 10:30 p.m. at everyone’s favorite hookah den, Mantra (52 Temple Place, Boston, 617.542.8111), give you a reason to do all of the above. Sip on a Mantra Mojito, Shantini, or Taj Mahal as you shake it to the spins of guest DJs. The catch: you’ve got to get on the highclass guest list at www.bostonviplist.com.
