Oobi and Kako are watching Grampu prepare spaghetti and meatballs in the kitchen. Grampu explains that it is for his upcoming dinner with Inka. He asks the boys to set the table for him. They bring a basket of utensils and glassware to the dining room. Kako invites the viewers to help him and Oobi place cups, forks, and spoons in the right order. Kako shows them the proper order, so Oobi tries. However, he can't remember what comes after the fork, so the viewers help him out.
Oobi gets the idea to turn the house into a restaurant for Grampu's date. Kako agrees with Oobi's plan and begins making the room look like a French-style café. Oobi names the restaurant "Chez Oobi". The next scene shows Grampu putting the finishing touches on his spaghetti and meatballs. He is called into the dining room by Oobi and Kako, who are now wearing bow ties. They have decorated the room with lights and outfitted the table with a patterned cloth. The boys welcome Grampu to Chez Oobi and explain what they have done. Grampu explains that tonight, they will have good music, good food, and good friends.
Inka rings the doorbell, startling Grampu. He rushes to the door and lets her in. Inka, who is wearing an orange dress for the occasion, looks around the room and is dazzled by the decor. Oobi and Kako direct the adults to a green radio and they go through a variety of music selections for them. First, they try soft violins. Grampu and Inka like it, but the boys don't, and they change the station to jazz music. Grampu and Inka like this as well, but the boys again change the station to "Itsy Bitsy Spider". The boys are happy with their choice, but Grampu tells the boys to go back to the soft violins. They do this and guide Inka to the table.
Oobi and Kako tell Inka and Grampu the menu, which consists of: spaghetti, spaghetti with one meatball, spaghetti with two meatballs, or their "special", spaghetti with three meatballs. They both order the special, and they drink while they wait to be served. They discuss places they have visited, such as Paris and St. Louis. Then, Grampu drinks all of his water, so Inka suggests they both share the same cup. Oobi and Kako promptly deliver their entrées.
Inka tells them "Bon appétit!", which she explains is French for "Good appetite". They repeatedly ask if the food is okay and are assured that it is just right. While Grampu and Inka eat, an interview segment plays. It involves Uma asking preschoolers about their favorite dishes. The scene cuts to Chez Oobi again. Grampu and Inka are seen sucking from a strand of spaghetti, seemingly about to kiss, but Oobi interrupts them suddenly with their dessert, fruit tarts, which they explain comes with the special.
Inka compliments them on their service, and she asks them to join them. They sit down, and they ask them about their experience. They explained that they had good music, good food, and good friends. Oobi and Kako congratulate themselves by doing their handshake, which they nickname the "Woo-woo", and they ask Grampu and Inka to do the same, as well a the viewers. The episode ends as Oobi, still dressed as a waiter, waves "goodbye" to the viewers.
