Sentence TL help

「ホントはシャンパンぐらい飲みたいところだけど、ジュースで我慢ねっ!」

Context: There's a welcoming party for some guy. The girl (who cooked all the food and prepared everything) says this to the guy at the party while they are eating and then pours some juice in his glass.

I'm mostly interested in 「飲みたいところ」and 「で我慢」parts.
Pretty sure 「シャンパンぐらい」means "at least champagne" or "something like champagne". If anyone could confirm, it would be great.

About 「飲みたいところ」, I don't understand the usage of ところ here. Also, what would be the difference if 「を我慢」was used instead.

Any help would be appreciated and if possible, keep it as literal as possible.

ところ here means something like "at/in this situation/occasion/point in time"
シャンパンぐらい is along the lines of "at least champagne" (implying a sort of minimum standard, although in this case the speaker is not serious). You might see things like "自分の部屋ぐらい自分で掃除しなさい!"

"I'd like to at least have champagne at this point..."

Xを我慢する can mean either that X is an unpleasant thing/situation that is endured, or refraining from doing/consuming X.
痛みを我慢する (endure pain)
お酒を我慢する (refrain from drinking alcohol)
So it doesn't really fit here.

Xで我慢する is often used when X is a less attractive option (but not by itself a bad thing) than the thing you actually want. It could be translated with something like "make do with/settle for". The thing that is being 我慢-ed is the lack of champagne; the juice is compensation to help put up with the lack of champagne.

Awesome, thanks for the help. :>
