I’ve spent way too much time experimenting with different drink and shake combos, and I’m here to share the best ones you absolutely need to try. So if you’ve ever wondered, "What’s the best drink to pair with my burger?", keep reading.

The Classic Drinks Menu

Before we get into the secret hacks, let’s break down the official drink options at In-N-Out. These might seem simple, but trust me, some of these pair better with burgers than others.

1. Soft Drinks (Soda Lovers, Rejoice!)

In-N-Out serves up all the classic soda options, straight from the Coca-Cola lineup:

• Coca-Cola

• Diet Coke

• Dr. Pepper

• Root Beer

• 7UP

• Pink Lemonade

Nothing fancy, but sometimes, a cold soda is all you need with a burger. If you want to mix things up, try half Coke, half Dr. Pepper for a unique blend of flavors.

➡ Pro Tip: Ask for extra ice if you like your drinks super cold.

2. Lemonade & Arnold Palmer

In-N-Out’s pink lemonade is a must-try, especially on a hot day. It’s refreshing, a little tangy, and not too sweet. Want to upgrade it? Try an Arnold Palmer, which is half lemonade, half iced tea.

➡ Pro Tip: If you like your drinks sweeter, ask for extra lemonade in your Arnold Palmer.

3. Iced Tea (For the Health-Conscious Crew)

If you want something light and not too sugary, go for the unsweetened iced tea. It’s simple, refreshing, and pairs well with a Protein Style burger.

➡ Pro Tip: Mix it with pink lemonade for a perfectly balanced drink.

4. The Most Underrated Option: Root Beer Float

This one’s a hidden gem. You can order a soft drink with a scoop of vanilla shake, and boom—you’ve got yourself a DIY Root Beer Float.

➡ Pro Tip: Works great with Coke or Dr. Pepper too.

In-N-Out’s Legendary Milkshakes

1. The Classic Flavors

In-N-Out keeps it simple with three flavors:

• Chocolate

• Vanilla

• Strawberry

They’re thick, creamy, and made with real ice cream—none of that artificial soft-serve nonsense.

➡ Pro Tip: Ask for your shake extra thick if you like a richer texture.

2. The Secret Menu Shake Combos

If you’re bored of basic flavors, In-N-Out lets you mix them up for some next-level creations.

Neapolitan Shake (The Most Famous One)

The Neapolitan Shake is a mix of chocolate, vanilla, and strawberry, and it’s perfectly balanced. Not too chocolatey, not too fruity—just right.

➡ Pro Tip: Swirl your straw around to get a different flavor in each sip.

Black & White Shake (Chocolate + Vanilla)

If you want classic flavors but with a twist, try a Black & White Shake—half chocolate, half vanilla. It’s basically a grown-up version of cookies and cream.

➡ Pro Tip: Add extra chocolate if you want it richer.

Strawberry Chocolate Swirl

This is for the fruit lovers—a mix of strawberry and chocolate that gives you a dessert-like flavor without being too sweet.

➡ Pro Tip: If you love chocolate-covered strawberries, this is your go-to shake.

If you’re more into sodas, the Arnold Palmer is the best refreshing option. And for those who love a little extra sweetness, the Root Beer Float is seriously underrated.
