The 18+ scene is Boston is pretty lackluster seeing as Boston requires that most places with a liquor license are 21+ which drastically limited the options for the 18+s. If you feel like spending a mint you could snag a ticket to the Dropkick Murphys weekend St. Patty's day shows but it will cost you an arm and a leg and is hard to manage since you aren't in the city to pick them up. You can also check out the Middle East in Central Square for a cheaper alternative.
As for lounges Ariberns covered some of the better ones. Have a good time in the city.
