If memory serves me right...they range from 4 beers in a bucket for $10 bucks specials to an average of $3.75 to $5.75..then if you want a call brand it runs a bit higher.
Sodas run under $2.00
A 15% gratuity is added to all drink bills.
Wines will run around $20 per bottle up to literally hundreds per bottle.

Now, others will probably provide far more exact info..remember, I was drinking all this time so I could be wrong!
