With the exception of our bowling and bocce leagues, the answer is no.
While we'd love for you to be able to play the leagues with a beer or seltzer in hand, unfortunately it is against the parks rules in this city. If our players are found to be drinking at our leagues we could lose out permits and our ability to run leagues at all.
In it's place, we try to set up a sponsor bar for each league that will give you deals to have a drink with your teammates and opponents before and/or after your games!
