Celebrity chef Tiffani Faison (pictured) may have braved such reality shows as “Top Chef,” yet her biggest task may be the debut of her third establishment in Boston’s Fenway neighborhood. Given her track record with nearby barbecue joint Sweet Cheeks and Asian eatery Tiger Mama, there’s little doubt that her latest venture, Fool’s Errand (1377 Boylston St., foolserrandboston.com), doesn’t live up to its name and is a smashing success. Built around the concept of an “adult snack bar”—an intimate stopover where patrons stand around communal tables and sup on small plates inspired by European tapas hangouts—Fool’s Errand also boasts a lively open kitchen and outdoor patio where visitors can enjoy the last bit of warm weather.
