This may be old news, but...
Just returned from Soi Samphanthamit. Today parking is on Nobi's side of the street, tomorrow Irish Clock side, etc., etc.
Of course, that didn't stop someone from double parking for 30 minutes in front of Nobi's.
Alternate Days No Parking Soi Samphanthamit
Sat having breakfast in Nobi's the other morning, found out those giant speakers outside D&N are for Tessa Bahn to advise residents which side to park. It went on for nearly an hour at full blast in Thai, followed by some stirring music. TIT So, learn Thai and get there early, you'll know where to park
