Hi :)

I want these expressions corrected, if there're mistakes.

It looks like we are going to have rain today.

Do you think it'll rain long? / Do you think we'll have the rain for long? / Do you think it'll rain for long?

(To a tour driver) Let's go back to our place. Let's give it about 30 minutes and go if it doesn't let up.

Is there any place selling Korean liquor? How far is it?

Sorry but can I trouble you for one more meal?

Are these right?
If not, please correct them!
Thanks!^^
