Olympic Cascade Drive-Ins is happy to announce that the Pasco Sonic Drive-In is under new management! But, don’t worry. We aren’t changing a thing. You’ll still get the same high quality service and products you’ve come to expect from us. You can still get the same Cherry Limeade and Half Price Shakes after 8 that you’ve come to know and love. So go visit our Facebook page and let us know what you love about us! Show us that Famous Slush on our page. Check in the next time you come on by Tuesday for a Half Price Cheeseburger. And let us know how we did with a review of how our great Carhops WOW you with our service. Along with our sister store in Kennewick, we here in the Tri-Cities still look forward to giving you Service at the Speed of Sound.
