Persist past the nasty on soi 4 for this hidden gem. It's a social enterprise of NightLight International, which helps trafficked sex workers get out of the industry. They also have delicious coffee!
From BTS Nana, take exit #1. Turn left on Sukhumvit Rd. Soi 4. Look for us on the left. We are across the street from 7-11 and between Heidelberg and Jools.
