I have mixed feeling about Jinmirak. The experience was ok but did not live up to my expectations:
1) They do not serve Korean beer, not even Japanese beer. This is pretty odd for a Korean & Japanese restaurant. Coors Light with my kimchi was a little odd.
2) The raw crab dish is seasonal (no mention of such on the menu mind you) and, you guessed it, I came when it was not "in season". Not sure what the season is either as nobody could tell me.
3) Apparently cold buckwheat noodles are also a seasonal dish (again, no mention of such on the menu). Although there were some noodles in a soup dish we got, I guess serving cold noodles is too much trouble unless it is the right "season".
The server was nice, and as previous reviews mentioned, it does get busy and hard to flag down service at times - but he was a good sport and was cheerful in the process.
The food we did get (not-BBQ, but other dishes to share) was well prepared. The side-dishes were fresh and replenished if necessary.
Jinmirak was cheap and we left full, so no loss in trying out a new venue. Not sure I would go back - but maybe just one more time to try the "seasonal" dishes (whenever they are in season - still no idea).
