Just back from the Community Medical Center at Lan Po seafood market in Naklua. Turned up just before 3PM Saturday, closed Sunday, and there was no queue. Two thai females walked in after me and they were in and out even quicker than me, which was no more than ten minutes.
Last time I went to the Lan Po seafood market the Medical Center didn't exist and I still have fond memories of the little park there, back when there was more grass and less concrete.
