Trying to find someone !

Hi,I worked in Halkidiki 20 years ago ,I’m trying to find a friend called Costa who had a place in Hanioti called ‘SPUD’.
They did jacket potatoes and you could drink there .Just up a side street up from the square .
It’s not there any more,I believe he moved back to Australia.
If anyone could help me I would be grateful ..
I worked in Polichrono at the sea-side restaurant,now called Viva restaurant.

Thanks

Gary
