Which sentence is correct English sentence???

Hi, three coffees, please.

OR...

Hi, three cupS of coffee, please.

Coffee is definitely an uncountable noun, but we often use it as if it could be counted. (I'd like two coffees, please.)

You cannot say "Three wines, please."

You should say "Three glasses of wine, please."

We do not refer to wine in the same way as coffee. The only reason I can think of is that for us, coffee is such an everyday, all over the place kind of drink, whereas wine can only be ordered in certain establishments, and it is generally a more elegant drink than coffee. The coffee may be served in a cup or a mug, or even a paper or styrofoam cup. But the wine will be served in a very special wine glass. They don't even serve wine in water glasses, so we would always ask for "a glass of wine," not just "a wine."

Your "and more" part is confusing to me.

"Three coffees, please" means that you want three cups of coffee. And you can ask for just that - three cups of coffee - if you want to. It assumes that all three will be the same kind of coffee, yes.

But asking for three wines (even if it were used by native English speakers, which it is not) would NEVER indicate anything about different wines when ordering them.

If you are talking exclusively about wine in general, and not specifically about ordering wine to drink, then yes, you can say "three wines" and this will indicate different varieties of wine.

Example: "Beringer is famous for three wines - zinfandel, chardonnay and pinot noir."

Number 1 is correct

Number 2 = Hi, three cup of coffee, please...

Just change the cup to cups

1.Hi, 3 cups of coffee please.

1.Three glasses of wine please.

Simple!

Hi, three cupS of coffee, please

The plural is what makes it correct. However the first one isn't ungrammatical. I've said something similar on more than one occasion.

The others:

Three glasses of wine. If you want different types of wine you need to specify, if it's all the same (IE: "Three glasses of the house red" then it's okay) you don't.

Hey dude make me up three cups a Jo and three glasses of wine and make it quick before I bust ya in the nut

say how many 'cups' of coffee or 'glasses' of wine you would like...but you must specify if you want three different kinds of coffee or wine if that is what you want.

1. Hi , three coffees please. (OK)

2. Hi, three cup of coffee, please. (cupS)

I think coffee is a uncountable noun in English.

What do you think about these sentences??

And more.

If I say ..

1. Three coffees, please. (OK)

2. Three wines , please. (OK)

This means,

1 three cup of same coffee.

2. three grass of different wine (no...you would get the same wine in all 3)

2. Hi, three cupS of coffee, please.

why you ordering 3 cups of coffee?

Probably No.1 is more common, but No. 2 is not "wrong".

And it would depend where you are. In Britain many people might start without "hi". "Hi" is typically American, but in recent years also used by youngsters in Britain instead of "Hello".
