Its a little early for me, but I remember the toilets were the other side of the bridge, which must be in front of the photo, As I do remember a sort of shelter in the centre of the grassed area of the park, but there again I remember a large mound which would have been to the left of the photo that was close to Edward Rd and was an air raid shelter entrance.
Most of the parks in the area in those days had large elaborate round shelters. I don't ever remember a café or tea rooms. I do remember the miniature steam train that used to run from one end of the park to the other alongside the Rea culvert. It was my favourite part of the park.
