Good settings, better than average local Thai food, reasonable price, good service.
I eat there occasionally and will go back.
There seems to be many return customers.

Approximate cost: $18

Having been to Malaysia 7 times I know that Jade Kingdom has some of the best cheap Malaysian food in Melbourne.
Friendly staff, laminex tables, great food, bustling atmosphere with many Malaysians eating there.

Approximate cost: $15
