Working in the Southside I get to frequent a lot of these establishments for lunch, so I do understand that the Double Wide caters more to the dinner and drinking crowd, at least I'm assuming this because the smell of beer still resonates when I eat there for lunch.
If you want to have lunch in the Southside and you want to sit outside there aren't many options, so Double Wide might be your only choice. If so stick to the salads as they are above average. Everything I've ever tried apart from salads though has been a disappointment, and salads aren't what I'm normally trying to order (even though it probably should be). If you sit inside though you will be greeted with a nice smell of stale beer that seems to have infested every inch of the place. It's a shame too, because I do enjoy the layout and atmosphere. If they just focused a little more on the quality and taste of the food I think this place would be amazing.
My recommendation is to avoid unless you really want to sit outside.
