What Is A Restaurant BYO?

Imagine walking into a restaurant carrying a bottle of wine.

In many countries, you’d be stopped at the door.

In Australia?

You might be thanked.

A restaurant marked BYO means Bring Your Own alcohol.

Many smaller restaurants don’t have a liquor licence. Instead of losing customers, they invite diners to bring their own beer or wine. The restaurant usually charges a small corkage fee to provide glasses and open the bottle.

It’s a particularly popular tradition at family-run Asian restaurants, where bringing your favourite bottle has become part of the dining experience.

Japanese restaurants in Australia were among the earliest adopters of BYO dining, helping Australians enjoy sake, Japanese beer and Australian wine together. Even today, many suburban Japanese restaurants proudly display “BYO” on their windows.
