Have you tried their app? I happen to live in Portland and work downtown.. the Starbucks at US Banc Corp Tower is probably the busiest in the city -- ordering ahead already saved me about 20 minutes last week.
Doomed to fail.
Its been a massive success for both employees and customers. This IS the way regulars will order for the foreseeable future.
Enjoy your wait in line.
