I think the first one means I had gone somewhere before I did sth else, while the latter one just express the place I went. I hope this will help you.

This is a very difficult question. "I had gone" is not easy English. For now, you should use "I went" for almost everything. If you want to know, I will explain it more. "I had (verb)" is for two actions in the past. We want to show that one action happened before the other. Here are some example sentences: -I had already eaten before I went to the park. -I had visited that restaurant three times before I brought my girlfriend there. -I had already gone home when she came to the party. Not easy, right? The important thing here is that the "had" part (had already eaten, had visited, had already gone) happened before the second action (went to the park, brought my girlfriend there, she came to the party). I think 90% of the time we use "I went" and 10% of the time we use "I had gone"

Jessica thank you

在汉语中通常要看上下文和语境来判断意思。

I had gone would only be used if the person then said that they returned later. Hope this helps!
