Delmar's Deli-Grocery was a local bodega owned by Delmar.
Delmar ran and operated a deli in Queens, with his sandwiches being touted as the best the borough had to offer. Peter Parker was one of his regular customers, who visited after school to buy food. Parker's frequent visits caused him and Delmar to form a friendship, as well as familiarize Delmar with Parker's aunt May. Delmar also came to know Aaron Davis as well due to his frequent visits to the Deli.

As the Spider-Man attempted to foil their heist, a powerful blast set off, slicing through the bodega across the street. Miraculously, no one was harmed."
