Belikin is $5 BZ in most restaurants and bars. Once in a while you will find it for $4 BZ.
Rum and Coke or other soda is usually $3 or $4 BZ and Rum and juice - $6 BZ.
Mixed or frozen concoctions are anywhere from $8 to $12 BZ depending on where you are buying it from and how many shots are in that particular drink.
Top shelf brand Liquor...(anything that isn't local) is also between $8 and $12 BZ a shot.
I learned to like Rum and Coke real fast....LOL
You can get a better deal on beer if you go ahead and buy a case from the distributor and keep it in your room. It will cost about $38 BZ for the beer and another $10 Bz or so for the deposit on the crate and bottles. You can turn them back in b/4 you go for a refund.
Most hotels will order it for you and stock it in your room if you ask. Just make sure you agree on the price beforehand.
CHEERS!
