Casual, big, loud, and extremely popular, this upscale joint near Fenway Park features chef Tiffani Faison’s succulent barbecue and hospitable service. Faison, a graduate of TV’s Top Chef, brings a fun celebrity charisma to her restaurants. Her Southern buttermilk biscuits are so popular that in fall and winter the restaurant sells them as a breakfast grab-and-go option (call ahead to confirm). Faison also runs the equally well-regarded Tiger Mama down the block (1363 Boylston St.; tel. 617/425-6262). Its menu is Southeast Asian–inspired: crab and asparagus fresh rolls, claypot chicken, and spring greens pad thai.
