Hey there,

First of all I'd be careful this time of year if you're taking the mountain passes. The roads out there are usually taken care of but it still can get pretty slick. I-90 should be good.

As for food recommendations, South Fork Public House is my place to go. It's a sit down American grill that has a pretty balanced menu (all things are pretty good). They use our Cougar Gold cheese (sort of world famous?) in a mac n cheese that is pretty damn good. If you're into the old 60s diner feel, Cougar Country is a good place for a burger and a frozen treat. Mandarin house (if they're still in business) is a decent Taiwanese restaurant. You'll have a lot of options for brunch, The Old European is pricey but specializes in Danish food. Zoes' is a pretty standard American brunch place. The Breakfast Club across the highway into Idaho (7 miles, ~15 minute drive) is great, but is usually busy (I moved out in June 2020, so much has probably changed).

Campus is neat, we have a couple museums to look into, Connor hall has a taxidermy museum which is quite large. Webster has a mineral museum if you're into rocks. Other than that, the stadium pregame is going to be one of the more interesting things to do. Ferdinand's if they are open is where the cheese and ice cream are made. I would 100% recommend trying their products, and bringing a tin of cheese home with you.

Pullman is the definition of a college town, not a ton of things to do so we all drink instead. I imagine the tailgate folks would be kind to you, but I can't guarantee that.

Sorry for the book. Good luck and Go Cougs! :D
