How many drinks do they serve before your cut off ? Is there a limit ? I imagine

Only one drink per person at a time. You can keep coming back but only one at a time.

Until you show signs of intoxication. There's no set number of drinks.

They serve until you cannot walk.

Funny question!

Hahaha how many can you drink in an hour and a half. Im sure they are like a bar. They have the right to cut you off at any time.
