I went to Cafe Melba at Goodman Arts Centre recently with the dogs and here's my experience.
Cafe Melba was quite nice. It was nearly empty and there was an indoor air-conditioned segment and a wide open patio with lots of seats and looking out into a big grassy field. I was having quite a nice time and the dogs were walking around freely, exploring the field and the tables. Two of the staff were also pretty nice, providing water for the dogs and stopping by to pet them.
