Finally got to try Odd Seoul after hearing all the hype for months.
We waiting a very long time to get a seat (they guessed 45 minutes wait but it was closer to 90) but we passed the time at a bar nearby. Not the end of the world. As someone else mentioned, you CAN'T wait at the bar in the restaurant for a table to be ready. However, you can eat at the bar, if there is space.
The service was prompt and polite and the food itself was varied and interesting, though not as mind-blowing as some have said. Try the squash poutine, that was a big hit with our group.
