Friday and Saturday nights after nine may get a tiny bit dangerous as the alcohol content in the patrons goes up. In Honduras, empty beer bottles are left on the tables until the bill is paid, so you can get a very quick visual indication of where cooler heads will prevail and where tempers may rise just by looking.
Beers range in price from L12 to L30 depending on where you buy them. The cheapest way to go is to buy bottles from a store, however to do this, or at least to get the cheapest price, you need to have a supply of empties to exchange for new ones. You will have to pay more the first time to buy the bottles, but then you've got the cycle going...
Decent rum is incredibly inexpensive in supermarkets think $6/bottle for what would be $25 elsewhere.
Honduras has four national beers, Salva Vida, Imperial, Port Royal, and Barena. They are all quite similar, all lagers. Port Royal is a bit skunkier, and Imperial may be a bit more flavorful.
The local hootch, known as "guaro" presumably deriving from "aguardiente" fire water, comes in two brands, Tatascan and Yuscaran. This is cheap, strong cane liquor, the choice selection of drunks in Honduras. At 40% alcohol, a litre of this stuff could run you as little as a dollar. Probably best to avoid... or a one time occasion.
