B+
Strong where it counts. Nearly half of all stops see service every 15 minutes or better — Link and the downtown bus spine are genuinely frequent, and Night Owl buses keep the map covered around the clock — but weekends give back a fifth of weekday service as the commuter trains and express buses sit out.
