Please recommend good restaurants or cafes in Yeouido, Yeongdeungpo.

Does anyone know of good restaurants or cafes near Yeouido or Yeongdeungpo?

I also like places that are like a hideout only I know about.

I want to try food of quality that isn't a waste of money.

Since I like local restaurants, I can't trust the internet because there are many ads.

Please let me know if you happen to know.
