Can you walk up and order

Yes

You most certainly can (but not through the drive thru window, they have a walk up window, specifically for that.. )

Yep. That is what the walk up window is for

Seeing as how they're a 'coffee hut' and not a restaurant, yes you can get service by walking up to the window. If I'm not mistaken, some locations have a certain window for walk-up customers to keep them safer than standing in the drive thru lane.

No Dutch Bros doesn't matter if you ride a bike walk driving car still still give you a good coffee best in the West Doug ☕☕☕☕☕

Yes you can they are more than willing to take you order walking driving or riding a bike it doesn't matter to them :)

Yes you can :)
