What time does it open and close to vehicle traffic? Do cars parked on that liitle L shaped street get towed at the closed hours?

The sign says 7pm to 2am closed....(Google maps).... but since bars are supposed to stop serving at 11pm I doubt it is that late. Never seen anything being towed, but block the front of someone's business I expect it could happen. 

If this about short term parking in the evening:

better spend a few Baht (30 or 40) and park on a nearby hotel lot. E g. on Soi Lengkee.

Could even ask at Areca Lodge.

Never would I park a car on LK Metro.

 

The path from Soi Buakhao to the Billabong corner is a nono at any time. All narrow and many businesses open.
