In 2011, a couple of Thai friends took me to Chula Soi 20 for some Yen Ta Fo. They say it has since been demolished (the whole area) to make way for a new development. To discover more about Yen Ta Fo food stalls in Bangkok, click here.
Also, not far from the spot where we got the noodles at Chula Soi 20 was a spot where we got some wonderful iced desserts (see below). And just a few doors down was a place known for its grilled bread with sweet creams. Click here to learn more about these two spots. We loved them....and now miss them!
