In The End
After All, Ultimately
adverb, noun
When you're in a bind, visiting the bureau may be your only option in the end. You were really hoping to avoid it, but it looks like you'll need to go after all.
結局 is used to talk about the final result after everything is said and done. It often carries the nuance that, despite the various factors leading up to something, things didn't go as expected or the outcome wasn't ideal, like 結局行かなかった (ultimately, I didn't end up going).
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. Note the けつ gets changed to けっ as つs in this situation often do.
