We've all been there, but let me paint the picture: you're miles deep into a road trip and suddenly want a milkshake while driving along Highway 101. If you're afflicted with milkshake cravings, then you'll want to make time along your trip to stop by Clarks Restaurant in Washington. This iconic diner has been around since 1923 when it was just a humble tavern called Ma and Pa's. There are whispers that Clarks serves the best blackberry shake near me in Western Washington. While it might not be featured on many lists yet, as a longtime fan, I wholeheartedly agree!

Located just off the highway, Clarks Restaurant in Cosmopolis, WA is an easy solution to the growling stomachs that can spell disaster on a road trip. If you're on a tight schedule, don't worry. The restaurant has a drive-thru for grab-and-go diners!

If you do have the time, however, I recommend sitting inside. In an age where restaurants strive to meet the latest trends, Clarks Restaurant in Washington is a refuge for nostalgia. Because so many of their regulars started coming as children, the current owners say they haven't changed a thing about the interior since they bought the place in 1997.

Some of what makes Clarks unique is their dedication to doing things the old-fashioned way. Their famous blackberry milkshakes are no different. All 30 flavors are made from ice cream Clarks whips up in-house.

If you don't have a sweet tooth - no problem! Clarks' large menu will please even the most discerning customers. Those in the know typically pair their blackberry shake with a deluxe cheeseburger, but staples like the BLT are equally good, if slightly less calorically intensive.

A visit to Clarks Restaurant is a visit to the past. After its tenure as Ma and Pa's, the building exchanged hands again. For the entirety of the 1950s, it was known as Wolfs until John and Beth Clark purchased the business in 1963, renaming it Clarks. The couple owned Clarks for 20 years before retiring. Kathy Pacana had fond memories of working at Clarks in the 70s, so she purchased the restaurant in 1997 with her husband, Rich. Together they brought Clarks Restaurant back to its roots of traditional American cooking.

Kathy was taught by John Clark himself to make ice cream following a recipe passed down to him by his grandmother. This personal touch and family knowledge is the special sauce that makes visiting Clarks worth a detour. It's also why they have the best blueberry milkshakes in Washington too.

A trip along Highway 101 will lead you to countless gorgeous overlooks and stunning parks. It can also direct you to some of Washington's most iconic, underrated restaurants. However, even among these gems, few businesses can compete with Clarks Restaurant's 100+ year legacy.
