This was something I was genuinely excited to try while in Bangkok, took a Grab across town to make it happen, but it was it is honestly not good, the Google reviews seem to coincide with the consensus that while the concept is cool, the execution isn't and it tastes very meh.

I do wonder if there’s some pluralistic ignorance going on, where travelers convince themselves it must be amazing because everyone else seems to think so.

It didn't give off the vibe of years of collected flavors; it was a thin broth and it didn't taste like much else other than beef broth from a fancy instant noodle packet and a ton of MSG (and to be clear, I'm normally a proponent of MSG but it genuinely was overdone here).

Maybe it really is just the volume that they're going through that's affecting the taste and composition, because they were doing decent business, but this was the biggest disappointment on my short visit to Bangkok.
