Flickr: mliu92 / flickr.co / Via Flickr: iamagenious / Creative Commons In-N-Out Burger's secret menu is so famous that the restaurant has taken to calling it its "Not-So-Secret Menu." The grilled cheese — two slices of American on a freshly baked bun served with or without lettuce, tomato, and onions — is guaranteed to please your little one. 2. You can also get a split shake or burger at In-N-Out. lammasagna / Via instagram.com You won't see this on the menu, but In-N-Out will happily split a shake at no additional cost if you have two little eaters with you. They'll do the same with a grilled cheese or hamburger, too. 3. The Sour Patch Kids smoothie at Jamba Juice. Renne Watkins @uilani66 Secret menu Jamba Juice. Sour patch kids makes my grandsons eyes go Kookoo😜 Fri Jul 08 20:06:15 UTC+0000 2016 Reply Retweet Favorite If your kids are fans of Sour Patch Kids, they will LOVE this smoothie. This is a popular secret menu item, so they should know how to make it, but if they don't, show them the recipe here. 4. The Skittles smoothie at Jamba Juice. Twitter: @RobinWithAnI A smoothie that tastes like Skittles? Where was this when we were kids? Again, you might want to have the recipe handy when you order it. 5. There are also four different gummy-bear smoothies at Jamba Juice. Twitter: @AbbyDidThat Warning: These are super sweet — which your kids will love, of course. You can get chocolate, green, pink, red or white. 6. The Cotton Candy Frappuccino at Starbucks. lindatejaa / Via instagram.com This is really just a Vanilla Bean Frappuccino with raspberry sauce, but it looks — and tastes — delicious. What kid wouldn't want to drink cotton candy? 7. The Cap'n Crunch Frappuccino at Starbucks. mxdnativebeauty / Via instagram.com If you kid loves Cap'n Crunch (duh), they will want to try this yumminess. Here's the recipe in case your barista is like, "The Cap'n what?" 8. And — oh my gah — the Twix Frappuccino at Starbucks. kkirookkirook / Via instagram.com Forget the kids — adults are going to want this one too, which is basically a Caramel Frappuccino taken to the next level. Here's the recipe. 9. A single taco at Chipotle. vsgkarina / Via instagram.com If you don't want to go all out, you can order just one taco for $2.40. Perfect for light-eating kids (or if you're bringing it home to serve with your own drinks and chips). 10. A grilled cheese at McDonald's. Twitter: @Secretfoodgems Ask them if they can toast the bread on the grill so that it doesn't end up being just a cheese sandwich (although your kids would probably like that, too). 11. You can also buy just the toy at McDonald's. teolinfeng / Via instagram.com This isn't a food item, obviously, but McDonald's doesn't publicize the fact that you don't have to buy an entire Happy Meal to get the toy. You can order just the toy. 12. A kids patty melt at Smashburger. BuzzFeed If you add a hamburger patty (for an additional $1.50) to a grilled cheese, you can make a super-tasty onion-free patty melt. And if your kid likes onions, you can add those too. Here's another off-the-menu secret about their grilled cheese: You can substitute the two slices of American it comes with normally for any of the cheeses they have (Swiss, cheddar, pepper jack, etc.). You can even get one of each if your kid would dig a cheddar-and-Swiss grilled cheese, for example. 13. A peanut butter–and–chocolate shake at Smashburger. BuzzFeed It's like a Reese's Peanut Butter Cup in shake form. They're also able to make your kid a PB&J shake if you ask. 14. Lastly, there's this secret menu item a junior high schooler I know swears by: the Meat Mountain at Arby's. sushibyterry / Via instagram.com This sandwich has ham, chicken tenders, roast beef, turkey, Swiss cheese, corned beef, Angus steak, brisket, cheddar cheese, and bacon on top. Your kid probably won't finish it, but they'll have fun trying.
