If you’re not spending your Cinco de Mayo doing the typical social events, such as A Special Evening with Frankie Valli & The Four Seasons at the Meyerson or The Salvation Army Women’s Auxiliary Fashion Show and Luncheon at the Hilton Anatole, spend the evening from 4 p.m. t0 2 a.m. at Mattito’s celebrating the Mexican holiday with the salsa and meringue band Carabali, plenty of rumbaritas, and a mechanical bull. By the way, the bull is sponsored by Tequila and has a mean buck.
