The green mini-buses of Mai Linh company are faster as they do not stop to collect passengers along the way. If these are full, the marginally-cheaper local bus also plies the route. It is best to wait for the bus in one of the cafes on the road leading out of the bus station, since the bus will crawl out of the bus station at the scheduled departure time, but take 10-15 minutes to reach the main road as it tries to drum up more passengers.
