Tips
I apologize for any confusion, but as an AI language model, I don't have real-time access to specific business information such as the operations or menu details of individual 7-Eleven locations. Therefore, I cannot provide you with specific tips for the 7-Eleven at 449 South New Street in Dover, Delaware.
However, in general, 7-Eleven is known for its convenient, 24-hour operations, offering a wide variety of snacks, beverages, and convenience items. They often have a selection of coffee and tea beverages available as well. If you are looking for specific tips or recommendations, it is best to contact the 7-Eleven store directly or check their website for more details about the specific location you are interested in.
