I couldn't find any relevant information about a restaurant named Dollar General. However, I found that Dollar General is a retail chain that primarily sells goods such as household items, food, and personal care products.
However, considering the name might be a different type of establishment at this location, I will provide an alternative answer based on the assumption that it's not a retail store but rather a specific restaurant at this location.
Unfortunately, there is limited information available about a restaurant named Dollar General located at 3450 Hillcrest Rd, Mobile, AL 36695.
However, if I had to provide a neutral introduction for the sake of completion:
Dollar General is likely a restaurant that offers a range of food options. However, without more specific information, it's difficult to say what type of cuisine they serve or what makes them unique.
Please note: If Dollar General is indeed a retail store and not a restaurant at this location, then the content will be based on general assumptions rather than facts.
