Rampo, that's the current/old address that we're not sure about. The old, old location was at Sukumvit Plaza, near Nice Guys. I'll drop by and have a look, but if open then it would rank about 3.5* on Icon's scale, by Icon himself...but I do recall he got the mamasan brush-off last time he was there, when they were not quite sure if they were open or not.
What about that dreamy place up Ekamai(?) or somewhere similar on a bend in the road near a hospital. Is that still in operation?
