I would definitely recommend Bodean's in Balham at 225 Balham High Rd, London, SW17 7BG. It has a range of dining spaces outside and in, including a banqueting table that can comfortably seat 12. Its BBQ ribs, pulled pork and steaks are second to none, the cocktails are amazing, the craft ales and a tremendous array of bourbons at the bar add up to bloke heaven, and on Thursday evenings there is even great live music at no extra charge. The service is efficient and friendly, and the value is pretty hard to beat. I go every week!
