In this sentence (from a manga), what does 所があるじゃない stand for? I don't seem to understand the grammar behind it.
それにしても鬼灯尹も結構可愛い所があるじゃないか。
(I mean, I know about 所が meaning however, 所がある meaning 'there is', じゃない as ではありません, but that seems to be something else here.)
According to JMDict, one of the meanings of 所 is as follows:
Therefore, in this sentence, "可愛い所" means something like "cute side".
One could translate just that part of the sentence as follows:
可愛い所があるじゃないか
isn't there a cute side?
Specifically, the speaker is saying that there is a cute side to 鬼灯尹.
Related question/potential duplicate:
Assuming 「鬼灯」is a name, it's a way of saying he has many cute things to him/her.
あるじゃない
Ending with じゃない in question form is like saying "isn't it?".
いいじゃない！ That's good isn't it?
Note: the negative would be よくない！
Also, よくないんじゃない！ That's bad isn't it? or "That's not good, is it?".
可愛い所 already answered by another comment, but you can use 所 to talk about "aspects" of something or someone.
優しいところが好きです。<- I like how (you/he/she) is nice.
