They opened up a quite large Italian restaurant directly next door to the cafe/fish and chip shop in the late eighties.
I take it from Autolycus' reply that it's not there anymore - I hadn't noticed.

I must have a look next time I'm in the vicinity. I don't know whether they overreached themselves with the restaurant or they sold out for large sums of money and retired to live the good life on the proceeds.
The original shop did an excellent haddock and chips - my first full-time job was across the road, and I used to go there regularly.
I got on quite well with the son who worked in the cafe, who I'm guessing would have been the one you went to school with.
The Hamilton shop was at Peacock Cross, and was still there the last time I was in the area a couple of years ago. The shop next door was the only place in the known universe that sold Hamilton Academical shirts, one of which is the only item of sports wear I have ever possessed.
