Can't comment on the authenticity of this place beyond mentioning that it seems to be family owned and they all speak Korean XD
Food is not amazing, but not bad either. Portion sizes and taste are standard and same as the Korean restaurants downtown. We didn't like the raw crab as much as we thought we would based on all the online hype. For $16 the portion size was tiny; in particular we couldn't access much of the crab meat in the shells. My seafood vegetable tofu stew was pretty good! A bit spicy, lots of squid. The seafood pancake was also a highlight. It was less battered than what we normally see at Korean restaurants and has big chunks of squid. It was also a big portion, great for sharing with multiple people.
The banchan (side dishes) were big portions and tasty.
Probably won't be back since so far out of the way and food is generic.
