I couldn't find any relevant information about a restaurant named "Dollar General".
However, Dollar General is actually a discount store chain, not a restaurant. It's possible you're looking for the cafe within one of their locations, which they call "DG Market" or "Dollar General Market Cafe", offering a limited selection of prepared foods and beverages.
If that's the case, here's a summary introduction:
The Dollar General Market Cafe is a convenient option for those in need of a quick meal. Their menu features a variety of sandwiches, salads, and hot entrees made fresh daily.
