At Buster’s Southern Barbeque, grill tenders transport the cuisine of the American South to the Napa valley region with a menu of juicy barbecue eats. Slow-cooking hot links ($3.50 each), chicken ($11.50 for a whole, $7 for a half), and racks of pork ribs ($21.50 for a whole, $11.50 for a half) sprawl supine on an open grill that effuses a mouthwatering scent of meat and a nose-tickling quill of smoke. Thick slabs of garlic toast trap generous portions of sirloin steak in Buster’s specialty tri-tip sandwiches ($7.50), which come slathered in the joint’s signature hot sauce, or mixed with milder condiments for a carefully calibrated pep. In addition to dishing out tasty meaty treats, Buster’s satisfies the near-inaudible mewling of sweet teeth with hot drinks such as café mochas ($2.50+) or frosty milk shakes ($5).
