Aquatic restaurant

The under the sea restaurant is an upscale eatery that sells sea food.

Appearance
The main dining area has light blue walls, a white ceiling, and wooden floors, with a fountain and various ocean-themed decorations (e.g. shells, starfish, tridents, etc.) scattered throughout it. The circular tables are covered with cloths, white in color with a single light blue stripe toward the bottom, and some spiked glass centerpieces, and most of them are surrounded by two blue, cushioned chairs. Booths are blue in turquoise/teal color, some in raised alcoves, accessible through drawn white curtains. The kitchen is entered through pale blue double doors with circular windows. The exterior has yet to be seen.

History
In "The Hand That Rocks the Mabel," Gideon Gleeful takes Mabel Pines there for their first date. While the latter is initially impressed (e.g. by the soda water and number of forks), she later comes to resent coming. After their waiter takes their orders, Gideon shoos him away. After the two finish eating, Gideon asks Mabel out again, this time to a ballroom dance, and she agrees only due to the pressure put on her by other patrons.
