We saw a sign for a bar that said "beer/soju/nacho/quesadilla"... so we had to go check it out.
So each bar always gives you some little complementary snack to eat. Sometimes it's peanuts, sometimes it's cracker-like objects, and in this case, this was really similar to breakfast cereal. The texture was that of puffed corn (maybe like Post Honeycomb, but without the sweetness, and maybe a little less dense), and the coloring is consistent with Kellogg's Froot Loops. Not bad, not good, but visually entertaining at least.
So the menu was in Korean, but I was able to identify: 멕시칸 나초스 (Mek-See-Kan Na-Cho-Suh), or Mexican Nachos. So we had to order it:
The nachos themselves were closer to toasted pita points or something like that. They certainly didn't seem to be made from corn. Also interesting is that it's served with pickles on the side, 'cause nothing says nachos like pickles! Like the cereal stuff, it wasn't that great, but it wasn't offensive either. Probably won't order it again though.
