Marge wants to be as fun as Homer so she, Bart and Lisa taste foreign food. They became foodies. They got an invitation to the famous restaurant in town but Marge didn't want to invite Homer and told him the wrong address.
After Homer takes Bart and Lisa on a fun dad day at E4, they come home and Marge tries to deflate their toys and ruins their fun day. Realising the kids don't consider her to be fun (Not helped by the fact that Homer says its his job to be the fun one and for her not to be), Marge wants to take them on a fun mom day and takes them to what she thinks is the X-Games, but it turns out to be the Cross Games, a Christian conference, where Reverend Lovejoy forces them into a nativity play (All the other kids are at the actual X-Games). As they are driving home, a squirrel crawls into Marge's engine and the car breaks down in the middle of the highway. There is a little juice left, and they drive into Little Ethiopia to find a mechanic. They look on the main street and see the Haile restaurant. Bart and Lisa go in, and reluctantly, Marge does too. Trying to be exciting Marge orders the more exotic item on the menu, and to her delight she and the kids enjoy it. Then, foodies, such as Sideshow Mel and Comic Book Guy join them. They accept Marge and the kids into their foodie group, and they create a blog about the exotic food they eat, called "The Three Mouthketeers". The next day Homer catches Bart and Lisa enjoying the leftovers of their meal and critiques it, voicing his dislike of new or exotic foods over the fridge and burgers, though he is obviously jealous that the kids would rather spend time with Marge than him.
Marge, Bart, and Lisa keep blogging about their food until they are invited to El Chemistri, the most exclusive restaurant in Springfield. Homer persuades Marge to invite him, and he accepts. Later that night Marge has a nightmare where Homer steals her thunder again, before her dream her dream is taken over by Gorden Ramsey. As Marge is giving Homer the address over the phone, she says 1501 East Oak Street, on the opposite side of Springfield, to mislead him. As Homer arrives, Meth Guy offers him drugs for $50, along with the other meth users in the lab. Then, police come and raid the lab. Then, at El Chemistri, they eat exotic foods, and Marge realizes her mistake, after Homer calls her and says that police are at the lab and are shooting the druggies. Marge and the kids rush there, and the police arrest Meth Guy. Then, the family goes on a family fun day to Krustyland.
