From left to right (in descending size order), I tried lemonades from Wendy's, Burger King, Chick-fil-A, McDonald's, Sonic, and Panera.

I opted for a medium or regular size from each location. When chains offered different flavors of lemonade, I went for the classic option.

Wendy's actually has an entire lemonade menu, called Dave's Craft Lemonade Menu, which offers four kinds of lemonade: Tangerine Twist (new this summer), Pineapple Mango, Strawberry, and All-Natural, which is what I ordered.

A medium lemonade at my local Wendy's on Long Island cost $3.69. At 32 fluid ounces, it was the largest drink of the six, and technically the best value.

This didn't taste bad, exactly, just bland. Fans of seltzers like La Croix and Spindrift might prefer this lemonade, since it wasn't overly sweet — it just tasted very watery.

This might also be a result of the cup's size. It required a lot of ice to fill up, which could've watered my drink down a bit.

Wendy's did not respond to a request for comment from Business Insider.

I ordered a regular Agave Lemonade from Panera, which cost $3.29. It was one of the smallest cups of lemonade I bought, at 20 fluid ounces.

According to Panera's menu, its lemonade contains "lemon juice, sugar, agave nectar, and water " — and no artificial sweeteners.

Maybe I've just had one too many margaritas, but the agave taste was not for me, and the aftertaste was even worse. It was so sugary that I felt like a cavity spontaneously formed in one of my molars.

Between its sweetness and relatively small size, I can't recommend this lemonade, but maybe agave lovers would enjoy it.

Sonic has a ton of lemonades and limeades to try, including cherry, strawberry, cranberry, blueberry lavender, dragonberry, and more.

I paid $4.29 for a medium All Natural Lemonade at Sonic, which is 20 fluid ounces. That made this the most expensive and one of the smallest lemonades I tried.

I think this was one of the sweetest lemonades I tried, but I didn't hate it.

What really puts this at No. 4, though, is the value. It was more money for less liquid.

As a kind of control group, I wanted to add a chain that doesn't have a proprietary lemonade recipe and instead uses a mass-produced brand like Minute Maid.

A medium lemonade at Burger King cost me $2.59 for 30 fluid ounces, making it the cheapest one on this list.

This was a perfectly average cup of fast-food lemonade. It was a bit sweet and artificial tasting, but it was essentially what I expected from Minute Maid and Burger King.

The value is what bumped this up to No. 3.

A medium lemonade at Chick-fil-A set me back $3.42 for 20 fluid ounces.

Typically, I'm not a pulp person. However, it surprised me to have some lemon pulp in my lemonade, and it made me feel like I was drinking a freshly squeezed cup of lemonade — it tasted like it, too.

Besides the texture, my other complaint about Chick-fil-A's lemonade was that my ice melted way too quickly. It was almost entirely gone by the time I got home — and it wasn't just because it was a hot day; all the other lemonades I had remained full of ice.

Chick-fil-A uses nugget ice, which is essentially small, chewable pellets of ice. Sonic uses that ice too, but for some reason — maybe the cup? — its ice stayed intact. The other chains used normal cubes or crushed ice, which also did not melt as quickly.

Chick-fil-A did not respond to a request for comment from Business Insider.

In April, McDonald's replaced the Minute Maid lemonade it had been using with a new offering called Premium Lemonade.

The Premium Lemonade has "lemon juice, lemon pulp, and cane sugar" in it, the chain said at the time.

I paid $2.89 for a medium, which is 21 fluid ounces.

I took a sip of this and immediately thought to myself, "This is what lemonade should taste like."

It was crisp, not too sweet, not too bitter, had the perfect amount of ice, and tasted like a sip of summertime.

And at $2.89, it was the second-cheapest lemonade I tried. You can't go wrong with this option.

McDonald's did not respond to a request for comment from Business Insider.

All these lemonades have something to offer, whether it's a cheap price, varied levels of sweetness, different types of ice, or different types of sweetener.

But, if I had to pick one, McDonald's would be my recommendation for anyone in search of a cool glass of lemonade on a hot summer's day.

Smashburger, a Colorado-based chain now found across 34 states, sells a BBQ bacon smash burger for $10.86, excluding tax and fees, at my nearest location in Brooklyn, New York. It was the cheapest of the three burgers I tried.

The burger came topped with cheddar cheese, applewood smoked bacon, crispy fried onions, and barbecue sauce.

Beneath a pile of crispy onion bits, I could clearly see the barbecue sauce, although overall, the burger looked and felt a little dry when I picked it up.

The crispy onions seemed to soak up a lot of the moisture from the beef patty and the sauce in my mouth, leaving a dry bite.

I'm not a fan of any burger cooked past medium, so this well-done patty simply wasn't doing it for me, but how a burger is cooked is a matter of personal preference.

The cheese on the burger I tried also wasn't melted enough to provide enough moisture to counteract the dryness of the burger.

However, the bacon on this burger blew me away. It was smoky and perfectly cooked.

I ordered the BBQ bacon Whopper Jr. and added cheese. It cost $11.09, excluding tax and fees, which I thought was a little pricey for a junior-sized burger.

The burger was served on a sesame seed bun and topped with barbecue sauce, mayonnaise, pickles, and strips of crispy bacon.

There was a generous amount of all the toppings, creating a balanced bite.

The bacon was crispy, though not as flavorful as the bacon from the other two burgers I tried. However, I thought this was a great classic cheeseburger. The onions, lettuce, and tomato were fresh, and the beef was juicy while still retaining a smoky, chargrilled flavor.

However, it tasted similarly to a classic Whopper, and I didn't get a strong barbecue flavor from it. It was a classic cheeseburger, but I was looking for more barbecue flavor.

Shake Shack, which has US locations in 30 states and Washington, DC, offers two different kinds of barbecue burgers: the Smoky Classic BBQ burger and the Carolina BBQ burger with fried pickles.

I ordered the classic version, which is topped with fried onions and bacon. It cost $13.29, excluding tax and fees, making it the most expensive burger of the bunch.

The barbecue sauce evenly coated the soft, fluffy bun and all of the toppings.

I was impressed by the size and thickness of the pickle slices, as well as the amount of crispy onions and bacon stacked on top of the burger patty.

The cheese was evenly coated on every inch of the thin, crispy patty, and the bun held everything together while still retaining its softness.

Though thin and crispy, the burger was still perfectly cooked at a medium temperature, and the onions, though crispy, weren't hard, crunchy, and dry like the onions on the Smashburger cheeseburger I tried.

Rather than bits of cut-up onions that didn't have much flavor, these onions were more similar to onion rings, and instantly transported me back to summer carnivals and roadside stands.

The pickles added a tart, crunchy flavor, and this was the only burger where I really tasted the barbecue sauce. It was smoky yet light and had a slight vinegar taste that balanced out the richer flavors of the cheese, beef, and bacon.

Though it was the most expensive burger, I thought it was well worth the slightly higher price.
