Good news; the One Dollar cafe was closed down for a while but has been renovated and has opened up again under a new name as of around 11 October 08; Khao Hom
Directly opposite Nara Garden hotel, where the Bangkok Airways staff is at home.
The food is decent and very cheap and lots of locals come here to eat, including lots of Bangkok Airways staff, who live across the road. Most meals are within the 40 Baht range, as the name suggests and offer good value.
It's a fairly simple affair, just a roof and some pillars, almost open air. It's very pleasant although in the evening there can be a few mossies out and about. Opening are roughly from 9am to 9pm.
If you're in the neighbourhood, definitely worthwhile checking out. My fave here is the Penang Curry.Camille
