Barbecue should always begin and end with the nose. The smoky aroma will lead the way as you're cruising along NE 167th Street. When you arrive at Bo Legs, someone will be manning the grill and the chatty lady at the counter will ask you a million personal questions and provide you with these sage words: "Chicken is the weekday must-order item. Ribs are for the weekend." There you have it. Barbecue or jerk chicken is $7, and ribs are $9. The sauce is the key to the meat, so squirt away. Sides are $3 for small and $5 for large. The mac 'n' cheese is a favorite that boasts a tasty tang from Muenster cheese and plenty of pep from black pepper. Even after you lick your fingers, the scent lingers. Sniff on.
