Trattoria di Monica opened in 1998 after its fraternal antecessor Vinoteca di Monica moved to a larger location on Richmond Street. Trattoria di Monica is located in the North End of Boston at the corner of Prince and Salem Street. Much to the pleasure of in-the-know fans, the storefront Trattoria di Monica is owned and operated by the Mendoza brothers. Chef Patrick and Frank Mendoza grew up in the North End and were taught culinary skills by their mother, Monica.
