Is good available to purchase at the venue?

There was a little cafe for food there.

Food to purchase at the venue?

Not sure if you're asking about tickets at the door or show merchandise, but I suggest buying tickets in advance through one of the ticketing apps, and the bands always have merch for sale. The last time I was there, in early March of this year, they were credit card only, no cash was accepted.

There is food and drinks to purchase there, and I will say it's a little pricey. It is to be expected.
