Traditional Shopfronts

In fairness, there is probably a little bit more to it than that Pot Noodle.

Say a Modern facade and an Irish bar going into it
how would you treat it old and new thats all

There’s no one answer to this. I’d go for something that compliments the existing building.
I do think that a traditional Irish pub facade, on an otherwise modernist building, would 99 times out of 100, look pretty stupid.

A perfect example Nash’s Pub besides St Patricks Cathedral cant find a pic at the moment
