T-Zero Lounge

Located in the lobby of St Julien Hotel & Spa, the T-Zero Lounge offers a modern, yet contemporary rendezvous for hand-crafted signature martinis, cocktails and one of the best wine programs in Boulder. Many of our drinks are made with local Colorado liquor and are complemented with an entertainment program featuring live music. T-Zero's stylish and secluded Round Room is the perfect place to host an intimate group event.
