REVIEW: Sonic Lemonberry Slush Float

Sonic Lemonberry Slush Float

What is the Sonic Lemonberry Slush Float?

Sonic has combined four summertime elements into one drink, from top to bottom: real strawberries, classic Sonic slush, 100% real ice cream, and lemonade slush.

How is it?

Since I had to get it from the drive-thru and bring it home (see below), I used my own straw and spoon to taste all the elements.

Sonic Lemonberry Slush Float Strawberry

The strawberries on top have the unmistakable flavor of frozen fruit. I don’t expect a national fast-food chain to use fresh berries, but I have never found frozen strawberries to taste that great.

Sonic Lemonberry Slush Float Slush

Below that, there’s the “classic Sonic slush.” Does that just mean a slush without any flavoring? Because that’s exactly what it tastes like: nothing. I guess it’s supposed to mix with the strawberries, but I don’t see the point.

Sonic Lemonberry Slush Float Ice Cream

The ice cream is what makes this a float, rather than just a slush, and it’s the reason you need a spoon instead of just a straw. It’s just what you’d expect from soft-serve vanilla. It’s enjoyable, but nothing amazing.

Since the lemonade slush was on the bottom, it was what I tasted when I stuck my straw into the cup and sucked. It was by far the best part -— tart, refreshing, and summery. Unfortunately, I quickly depleted the lemonade part and was sad when I only had the ice cream.

I had hoped the flavors would mix together better, but mostly I just tasted each element on its own, even when I wasn’t trying to keep them separate, and even though they looked like they were somewhat mixed.

Anything else you need to know?

When I pulled into a stall to order in the usual Sonic way, the red button timed out twice without anyone ever helping me, so I had to go to the drive-thru, where I kindly told them what had happened. Also, they gave me salt packets but no syrup for my French toast sticks. So, at the risk of sounding like a Karen, my experience at the Salt Lake City Sonic gets a 2 out of 10. Yelp review over. But I’m rating the drink on its own merits.


The Lemonberry Slush Float is fine, but next time I think I’ll just get a regular lemonade slush.

  1. According to the website, classic slush really is plain old unflavoured sugar slush. Seems like an odd choice for this drink. Who wants no flavour?

  2. It sounds like the better option is the fully mixed lemonberry cream slush, which is my favorite thing at Sonic, ever.

  3. I absolutely love this drink! i use the spoon to mix it slightly and then drink it all through the straw.
