That would be the Wellington cafe on the corner, really good chip shop and cafe. Usually have to wait for a table, that is always a good sign.Red (aka Ketchup) for sure
Mayo? you a blooming Dutchman??
There was a fish & chip recommended to me in Ayr Town. don't know the name but it is on a corner at a roundabout with around 5 or so roads (hopefully some can ID from that?). I was staying in a carpark overnight (doing some van electrics) and it was indeed very good as promised.
Gold Star Chip Shop Onions (the brand from that Glaswegian company) are sold in B&M Bargains in big bulk jars (not big enough though ... it ran out ) and I saw the Gold Star Brown Sauce in LIDL in Kelso (not seen it anywhere else).
