Super fun little place to stop and grab a quick lunch. We were in town heading up to a football game and I was beyond thrilled to see the million options for the milkshake flavors! Sadly, a milkshake wasn't in the cards for me that day, but I did order my other favorite and American classic, a BLT. My son got fish and chips Both dishes looked delicious when they came out and I quickly scarfed mine down. Could've used a little more mayonnaise, but this isn't the Ritz Carlton and I was pleased. even though our family is a huge fan of fish and chips, my son was not liking the entrée today. My husband tasted it to see and for some reason they just tasted a little off. He gently asked the lady behind the register if we could get something different and she quickly made us a cheeseburger and fries at no charge! Needless to say, we are in love with our customer service and we will definitely be going back to try all of the milkshakes

Nice people and great quality food , the smoothies and the milkshakes are very delicious. The cheeseburgers are always outstanding. The family owned restaurant has locals working here, they seem to be honest and respectful. I do highly recommend this place, if you haven't tried it; this place is located in the better part of Marysville California , by the old Gold Sox ball-field and surprisingly has a drive-through. If you haven't tried it, try the Purple Cow Milk Shake, I highly recommend it . Hey also the atmosphere there is great, wonderful energy.

The burgers are ok, I get the Bacon deluxe cheeseburger with mushrooms. Burgers are made right as you order them, the ice cream is ok to wish they had shaved ICE. The ambiance could also be better

Stopped by the Frosty's for the first time passing thru. Double bacon burger was good, my fries were hot and crisp and my shake was COLD! Place seemed pretty busy on a Sunday afternoon but we still got our food quickly. Staff was polite and the inside was well air conditioned! Not gonna put this at the top of my burger stands but I would return if in the area

Friendly and fast service. Delicious quick bites. Our go to when driving through Marysville.

Root beer float FTW! Stopped by passing through town and got (1) a great friendly cashier, (2) speedy service, and (3) excellent ice cream. What more can a person ask for when it comes to a root beer float order? They nailed it!

Great place for a classic American burger! They've got all the classics: burgers, fries, chicken tenders, fish & chips, and a HUGE selection of milkshakes with every flavor under the sun. Everything is made to order and tastes fresh. You can find the team's favorite items on the whiteboard on the wall if you need some inspiration among all the options. I got the deluxe bacon cheeseburger which was perfectly cooked with some perfectly melted cheddar cheese. My chocolate hazelnut milkshake was just the right level of sweetness, and the garlic parmesan fries had a ton of flavor. Service is fast and friendly. The family that owns this place is very kind and always strives to give the customers some great quality food. We got our shakes first and our burgers were ready soon afterwards. We didn't have to wait long for anything. Overall Frosty's is a classic old-timey fast food joint with a diner vibe. You can count on this spot for a solid burger and tasty shake. I'd definitely come back again next time I'm in the area!
