I will begin by clarifying that I am not Korean, so I may have different tastes than other reviewers about E-Jo. I ordered the Hangover Soup, and it was missing a certain something. I added kimchi into it, and it was a bit better.
The kimchi cabbage and the kimchi radish that accompany the meal were good, but it was not the best I have had. Once again, I am not Korean, so maybe that's what authentic kimchi tastes like. I have, however, had kimchi in Seoul airport before, and it did not taste like what E-Jo had to offer. All in all, I don't think I'll be returning soon.
