There are rooms in the Rink Building and also in the Alexander St building, but I am not sure of the availability and usage rules.
No need to rent it's free just beware of the people there
There might be at a local community center, however, this location is just an outdoor park, they have a pavilion, with picnic tables & chairs. I'm not sure if you have to rent & reserve it, as you do with some parks, or just use the space if it is open.
