We lived in korea for 3 years and went to these beef-n-leaf places quite often... yum! We were pretty happy when we walked in and everything was familiar, pretty darn close to being in Korea, except for the prices :)
Even the sushi was decent, the sauces are pretty authentic, the meats were all the same, marinated pretty darn close. Kimchi in korea was better, but that's a blip to this place that overall was pretty outstanding.
Servers were attentive. Place seemed clean.
We would definitely return here if we were from this area.
