Quest for Mexican Restaurant with White Cheese dip

You know the dip - comes out in a shallow bowl, searing hot liquid at first, but quickly congeals if you aren't consuming it quickly enough. This variety of cheese dip is easily found in the strip malls of most southern cities, Atlanta for example has them everywhere, in Mexican restaurants that have roughly 78 numbered order options which are really just five different entrees mixed and matched into different combinations. The sodas come out in gallon-sized plastic cups, and there's a dusty pinata hanging in the corner.

I don't want authentic. I don't want fresh. The quest for the perfect taqueria is better left to other threads.

I want this experience, and I know it has to exist somewhere in or around Washington DC. Come on foodies - help a brother out.
