Letters/X, Chicago’s favorite anti-Valentines day cabaret, is celebrating its fifth anniversary! Due to the overwhelmingly positive audience over the last four years, GroundUP is bringing back the most popular songs, and skits, and soliloquies. Letters/X, the popular cabaret based on actual love and hate letters, returns to the Hungry Brain pub to give you the best of its cross-sampling of love gone awry. This Valentine’s Day tradition will help confirm your decision to leave or to stay, and may clarify any lingering questions about your current romantic exploits.
