I went to this place tonight on 9/12 of 2026 to get a couple of treats I got a small mozzarella sticks and a small Heath bar blizzard and when I took a bite of the heath bar blizzard I immediately noticed that there was something wrong with it.. I spit the bite out in my hand and noticed that it had several small shards of jagged plastic. One of which I started to choke on I went to the door and opened it and told them there's plastic in this blizzard and I needed a piece of bread so that I could swallow the piece of plastic that was stuck in my throat and the girl who works there looked at me like I was crazy and kept saying go outside the door go outside the door even though I was choking on plastic. I brought it to the manager's attention he said he didn't know what the plastic was and he didn't hear the girl or see what the girl did or said I let him know that I would be calling corporates tomorrow morning.. use extreme caution when purchasing food from this location. It's staffed by teenagers including the manager. And they clearly do not care about food safety or customer safety....

Man! These guys are charging like 6 bucks for a soda now. A bit excessive! I never eat here because it seems expensive for what you get and the food is not that great. But , I am one that doesn't eat alot of fast food. I'd rather sit in a restaurant for a couple bucks more or for that matter the same price. Fast food places seem to be having a problem but, let's face it they are price gouging customers and it's not just Sonic!
