This weekend we had takeout and it was so good! Shmokey Rob n' Sons is in an old mall near our house. There's not much else in the mall but it's worth the trip.
I can't speak to how authentic their BBQ is, since I've never had the opportunity to taste real southern BBQ, but I can tell you their food is delicious. We've tried a few things on their menu, but our favourites (so far) are the brisket sandwich and cassava fries. (Cassava is a starchy, tuberous root that has a taste and texture slightly similar to potatoes but more starchy and firm. They hold up way better than french fries for takeout too.)
Aside from the brisket and pulled pork sandwiches, fries and cole slaw, they also have specials like ribs and "burnt ends" which are smoked, braised brisket ends. We've never had the pleasure of sampling them since they've been already sold out every time we've visited, but some day!
I had my brisket with some Julian Cherry Bomb hard cider which is deliciously tart.
If you live in London or come to visit, I can't recommend this place enough. The mall atmosphere isn't fantastic, but the place itself is super cute with table service and beer on tap as well as takeout. Give it a try!
