Since the first dinner that Triniti hosted along with local orchestra Mercury Baroque was such a success this past June, they're doing it all over again. This time, however, the dishes and the accompanying music will be all different. Via a press release, organizers say: ''[The event will be] pairing live music choreographed by Mercury's Maestro Antoine Plante to an eight-course dinner and wine tasting menu created by Triniti Executive Chef Ryan Hildebrand and Sommelier Fred Zennati. The dinner, Autumn Concerto in Eight Courses, will provide a sneak peek of what's to come on the restaurant's new fall menu, which will officially launch the next day, and promises to be a sensory journey of sight, sound and taste. Forty percent of all ticket sales will benefit Mercury by supporting the orchestra's concerts and vital music education programs.''
