The UFO has been many things. I think I remember a hot dog joint and a real estate office. I remember it being on the other side of the road up on its legs in a previous life.
I said "art gallery " but it is a place where you can go and make and paint pottery, plates, cups ect., I can't think of the name. There is also a coffee house (wifi) in that building. The old Outer Beaches Office is to right of Subway. The Subway building was at one time the Avon Post Office. JUST REMEMBERED the name Studio 12 Paint Our Pottery. IF you would like to go to a nice Gallery there is Gaskins Gallery on Northend Road Avon Village.
