Hi, many thanks for all the suggestions. We have actually tried the Balti house and thought it was pretty good. Will definitely try the Tandoori Oven and Ruby Raja for comparison though.
Tongue Tiad has also been suggested to us before as a good Thai so we'll be making a visit there as well.
Re playgroups, yes I've tried Playgroup SA and Adelaide's Child - either my son is still too young or we're not in the right area, always the way, but I'll keep trying.
Many thanks to everyone for all your suggestions.
