Does anyone know the average prices for: Domestic Beer, House Wine, Soda, and Premium Drink(ie Margarita)? Just putting some numbers together. Iam assuming its on the high, but just how high.

this link should give you an idea

Va_Cruise, Thank you. This is perfect

I was wondering the same thing, thanks for the link, the prices are quite reasonable I think!  are these just in the bars or pertain to the restaurant(s) as well?

Prices are ship-wide.  When you're in the formal dining room a drink girl will come around and ask if you want any alcohol drinks - if so, they'll be the same price as if you were in one of the bars or up on lido.  The only time drink prices will change is if they have a happy hour special on a couple specific choices.  Then that price will only be available for a limited amount of time.
