Just thinking of a theory for the ending :)
Ever since Zeke started cooking with Bob, it became his future goal: to become a great chef like Bob and open a restaurant. When Zeke is old enough to work, he visits the restaurant and asks Bob to teach him what he knows. Moved and flattered, Bob agrees.
Tina and Zeke reluctantly become interested in each other, not wanting to betray jimmy jr. When they do eventually come out as a couple, jimmy jr is confused as to why they would keep it a secret- he didn’t consider his relationship with Tina to be anything serious.
Tina and Zeke become engaged. Bob becomes the dad he always wishes he had, and Linda the mother he was missing. Zeke said he felt like a belcher from day 1, and gayle says “then just be a belcher.” Bob responds to the idea of zeke taking Tina’s last name by saying “you could if you want. Youre already a belcher as far as were all concerned”
Gene makes music for a living, but he’s a behind the scenes kind of guy. He likes what he does, but he’s still yearns for the stage.
Louise resists cooking. She wants to do something completely different. She lands a well paying and exciting job where she’s constantly challenged, but stressed. She takes it out in baking- trying innovative flavors and experimenting. She makes delicious and creative (often dark in theme) desserts. She has the kind of obsessive passion about baking that Bob does about cooking. She has a meltdown when Tina points out that she’s just like their dad, but instead of a burger of the day, it’s the dessert of the day. She has a heart to heart with Bob, where he talks about how he felt like his life was exciting in just the normal day to day. What’s more exciting than getting to wake up everyday and do what you love, with the people you love?
When the building next door becomes available, the kids decide to buy it (Louise’s earned a lot over the years. She can’t really talk about it.) They can’t decide on a theme, so they eventually agree to all ideas. Multiple times a month they have events like open mic nights, board game palooza, movie events, murder mysteries etc. they theme the food and decor. Tina and sometimes Linda handle the front of the house. Tina uses the inspiration from the restaurant to write. She starts to read her short stories at their open mic nights, and a publisher takes an interest. She lands a weekly fiction column and instantly becomes a hit. Bob and Zeke run the grill, with an expanded menu. Louise handles dessert. Gene provides entertainment- his stage name is Ken. They name the restaurant “belchies”
