The owners of Zahav and Percy Street Barbecue will be renovating their trendy restaurant, Xochitl, located in Society Hill. After it closes this Sunday, February 7th, Xochitl will bring on a new chef, new menu and a more casual look serving up cuisine seven days a week. When it re-opens on February 21st, the dining area will have undergone minor construction, tearing down the wall that separates the bar and dining area, going for a more casual dining experience.  Chef Lucio Palazzo, formerly of Zahav and Percy Street Barbeque, will replace Dionicio Jimenez, who decided to leave and take on other endeavors. Palazzo and the owners have been revising the menu and prices to complement the new atmosphere of the restaurant. One thing that will stay the same is manager Sergio Ruiz‘s famous cocktails and margaritas with a few new additions. Thanks to Ruiz, Xochitl was voted “best margarita in town” by US Airways magazine; in its soon-to-be ended present life, the spot also garnered acclaim from Philadelphia Magazine as one of the “Top 50 Restaurants of 2009.”
