Don't see why it's a proper noun and let's say roadside shop isn't. Could you explain please? For example, "You'll have to fight the boss at level 10" doesn't seem incorrect to me. I saw examples in dictionaries where the word was capitalized for diploma titles for example but couldn't find an example like yours.
