Interesting, I went to two other BBQ places on the same 3-day trip, Daedo and one other one whose name I am now forgetting, and I definitely thought B&B was a big step up in terms of the meat quality, so we just have a different point of view, as I definitely do not think "meat is meat." The handful of Korean friends / acquaintances that I met up with on that trip (and also some Korean friends here in the US) had either been themselves (and were the ones that recommended it) or knew of it as the premium hanwoo omakase place.
Of course part of the B&B price point is the ambiance, the chef and waiters that speak really good English, etc. and not just 4x the price for a commensurate 4x improvement in meat quality, but that's also the case with other high-end restaurants? I've never thought a Michelin restaurant that cost 5x a normal meal was 5x better food
