Other than some labs that also sell film, Michelle has it right. 35mm won't be a problem at either of those locations, but I'd call ahead for 4x5. National Camera has a few locations, but the Golden Valley location is best for 4x5.
If you'd like to order online and have it delivered to my place (I'm in Plymouth, just west of Minneapolis - in fact about 6 min from National Camera) PM me.
I also have some film in the freezer (HP5 35mm, APX100 4x5, some JandC 100), some in-date and some outdated, that you could "borrow" (i.e. replace) if you get in a real crunch or passing through when those stores are closed.
