Peace Diner

Restaurants are a kind of shop present in Persona 2: Innocent Sin and Persona 2: Eternal Punishment. By paying a small amount of money, any character can buy one of the dishes or drinks served there and get a temporary stat increase. All restaurants offer another service like selling weapons or being the place where a Rumormonger hangs out.

Trish's Fountain
At first, Trish won't sell ice cream. The player must first obtain a rumor about Trish selling ice creams from Demon Rumormonger Nekomata, located at the Kuzunoha Detective Agency, by donating 100,000 yen to the cat statue. Additionally, later in the story Nekomata will have another rumor available that claims she's reformed her greedy ways...sort of. The rumor has two possible randomly generated outcomes which both effect the cost of ice cream by either lowering her prices, or raising them, but adding "Lucky Ice Cream" and "North Light Vanilla" to her inventory.

Gatten Sushi
Found in the Lotus Plaza of Rengedai District. Rumormonger Toro is found here.

Izakaya Shiraishi
Found in Kameya Alley on the Hirasaka district. It's known as "Ramen Shiraishi" in Innocent Sin and serves a variety of ramen noodles, but changes to an Izakaya-style bar in Eternal Punishment which sells Japanese snacks and sake.

The owner is referred to as the "Shiraishi Lady". Although it may not have been her true backstory, rumors in both games make her become a former secret agent that sells weapons in her store. She also has a dream of publishing an autobiography of herself which can be realized through rumors in Persona 2: Eternal Punishment. Gradually throughout the game she tells a myriad of grandiose stories about her bizarre past including:


 * Reveals her last job as a spy was to investigate the presidents secret affair. However, she had personal problems during the investigation due to rumours of her being in a relationship with the president. In the end she admits being a spy was a hassle and not worth the trouble.
 * Involved in the Russian revolution in the first communist uprising. She claims that there was feature of her venture on a pamphlet at the Ho Tung Harvard university.
 * Ex-idol and was called the 21st century’s last idol or the nationalist knockout. She says she misses the glory days.
 * Had a brief career as a model and posed for several magazines, claiming she had walked in ‘Parish’ fashion week several times. She had personally tailored outfits from the high fashion brands Juan Galliano and Alexandra McQueen, which are names that can be linked to the real British fashion designers John Galliano and Alexander McQueen,
 * At 18 years old she broke into the Hollywood industry as an actress.

In order to get all the plates on the menu, the relevant rumor must be spread. Rumors must also be spread to add the Combo Plate to the menu. An extra sidequest line called "The Man Searching Quest" can be unlocked from which the Shiraishi Lady oversees.

Rumormonger Toku can be found here.

Peace Diner
Found on the Central Avenue of the Yumesaki District. Rumormonger Chikalin is found here. In Megami Ibunroku Persona the party cannot order food throughout the game, however, they can visit Peace Diner and talk to people.

Double Slash
Found in the Aoba District commercial area.

In Eternal Punishment, the Wang Long addict here will tell you which dragon rules over you by telling her your birth month. If you tell her HASTURCOMEFORTH (in all caps) she will panic, but you will be able to pick up the Material Card "King in Yellow" on your desk at Kismet Publishing, which is required to create the Persona Hastur in the Velvet Room.

Baofu's Rumors Websites can be accessed here.

Parabellum
Parabellum can be found in the Aoba District commercial area. Some time after the rumor about the Bar selling weapons and another rumor are spread, the rumor-loving Bartender moves from Narumi to Parabellum (along with all of her drinks). A rumor must be first be spread before "Front Sight" and "Rear Sight" appear on the menu. Tatsuya cannot purchase any of the drinks, as he is underage.

Johnny Roger's
Found in the Seaside Mall in the Konan district. The bartender also functions as a rumormonger.

Ebony
Ebony can be first found in the Hotel of the Narumi district. However, later in the game Narumi becomes inaccessible, obligating the Bartender, who is also a Rumormonger, to move to Parabellum (a rumor must be spread). After a certain rumor is spread, Salam will ask you to make maps of dungeons in exchange for Rare Spell Cards and Fool Tarots. Tatsuya cannot purchase any of the drinks, as he is underage.

Clair de Lune
Run by Garcon Soejima, it is first found in the Hotel of Narumi, and later found in Aoba after spreading a rumor. Clair de Lune can sell either armor or weapons, depending on the rumor that is spread.

Trivia

 * In Eternal Punishment, due to being a minor (below 20 years old according to Japan's law) and Katsuya Suou's presence, Tatsuya Suou cannot dine anything with alcohol in it. He is the only character in the game to have this kind of restriction.
