Grill 13 was a restaurant in Raccoon City. The kitchen had several propane tanks leaking gas and the basement is flooded due to a ruptured pipe. According to Marvin's Report, this restaurant was owned by a 42-year-old man. His name was unknown. During the outbreak, the owner took shelter in the R.P.D. in the morning but was shot to death minutes later after showing signs of t-Virus infection.
In Resident Evil 3, Grill 13 is one of the locations Jill Valentine visits while exploring downtown Raccoon City. Inside the diner, there are booths and tables that contain different brochures and items. In the back of the kitchen, a small locker can be found with a fire hook hidden inside of it that requires a lockpick to open it. The fire hook can be on a panel to gain access to the basement of the diner. Two Gun Powders A may appear on the table randomly. If they aren't, their location will be the office of The Raccoon Press.
Jill meets Carlos here, if she doesn't met him at the The Raccoon Press office already. Then they will be ambushed by the Nemesis. The live selection will appear, where Jill either has the option of hiding in the kitchen, in which she will use a nearby lamp to knock Nemesis out, or hide in the basement of the kitchen, where flood will occur because of powerful blow of propane tanks in the kitchen. Carlos and Jill can escape through a ventilation shaft near the large freezer or they can return and fight Nemesis. Also, the cutscene will appear, where Carlos talks Jill, that they must return to the kitchen, because of high level of water. The water in basement may be drained using the switch near the basement entrance. If Jill does not meet Carlos at the diner, then she will be able to obtain the green gem from the basement of the kitchen. Also, five zombies will be lurking inside the restaurant in that way.
During the Operation: Mad Jackal quest, the mercenaries can enter Grill 13 in route to their destination point. Inside the kitchen and dining area of the restaurant, a pair of Hunters will attack the player. In the basement of the kitchen, the player will come across a few zombies stalking Brad Vickers. Rescuing Vickers will reward the player an additional item and more time on the clock.
