There's actually many cute items in the Little Campers pack for Sims 4, that our Sims 3 deserve as well! You'll find a backdrop screen (requiring Into the Future), an open tent, toys, furniture... well, there's 18 new objects.
Mods / Traits 
Each cookie pack has its matching edible cookie (the Royal Danks even have 3!)
This is an object script mod for Custom Edible Objects, such as the food available from Around The Sims 3, One Billion Pixels, and Parisian Sims.
This is a script that can be applied to an object to turn it into a generic food maker. Using Buy/Build mode interactions you can configure what kind of food can be made
Where do I start? This mod is embarrassing at some many levels. The title is weird (I didn't know how to call it), the animations suck and I'm not able to do it as I'd really like to. So before I delete it out of frustration I better upload it.
It contains one chopstick only, because I wanted to be able to place two so that wouldn't seem too symmetrical. In the end I didn't used them for the story, but I include them in the download.
This mod adds a new, custom, hidden trait to help you bring a Japanese flavor to Sims. Why hidden? Alas, it was a very painful decision, but otherwise the game will assign it randomly to new created Sims and that will make no sense.
Sims 3 are luck, they have different ways to get their favorite drinks!
A collection file gathering all my teapots and cups (filled or empty, so it also includes old objects); I put each time the teapot near its matching tea cup.
Too late to cook? The pizzeria is closed? Buy a pizza at a vending machine! Yes, it's a real thing, there's one where I live, and it seems to be quite popular! :D
