Did you take a look at the restaurant reviews for Silverton? There's a link at the top of this page. If you arrive at the same time as the train you may not find any quick food and there's not any place like Wendy's, etc.
I can't think of any fast food in Silverton. Natalia's has a hot buffet and take out, but not sure I'd call it "the best." But they also have the adjacent Goodies to Go where we've gotten good coffee drinks.
Avalanche has coffee, plus sandwiches/wraps. Three Pitts Again has carryout BBQ. I'd probably just take time to eat there and then get coffee to go at Avalanche or Goodies to Go.
