This is just mostly for my curiosity, but I've been wondering what happened to a favorite hole in the wall from previous Tokyo trips.

I don't remember the name - it may not have had one!, but if you headed directly behind the Peninsula Hotel and turned left at train viaduct, the place was in one of the archways. I remember it was white - maybe tile, the name had numbers in it - 123?? - the food was Malaysian IIRC, and was very cheap. It would have been before the Bic Camera corner. There was always a line and you sat on chairs outside, moving along until your turn came. The food was very inexpensive, but they clearly made their money on the beer. Delicious. Our last trip we could find no sign of it whatsoever, but that area has had a lot of redevelopment. I miss it. Did they move? It seemed like the sort of place that had been there forever and would be there for a long time to come. We found nothing, no name with numbers, no white facade (tiled or not) nothing. Were we just in a beer haze? Maybe it's like Brigadoon and I just made up the whole thing?

I'm not sure how we found out about it to begin with, but suspect it may have been mentioned on a thread here!
