It’s been a long winter and pretty short spring, so summer deserves a proper welcome and Glass House is here to help. Mark your calendars for Saturday, June 1st and make your way to Kendall Square for a warmer weather party (yes, even before the official solstice — it’s never too early for short sleeves) from 2:00 to 6:00pm. Summer cocktails (think: frozen mojitos), live music, tons of family-friendly games (there’ll be a giant jenga, folks) and more will be part of the festivities, plus to-be-announced food specials. RSVP on Facebook, but note: admission is subject to available space so arrive on the early side to up your odds of entry.
