Hi ! welcome.
Although I now live in Whitley Bay, I was born in Newtownards and visited Bangor many times. My Grandma lived near Ward Park. I actually lived in Holywood until moving here with my parents. I was in Bangor nearly every year, until my grandma died about 3 yeas ago. The new marina is nice too and good to see the old clock wasn't removed.
Would eat 'champ' in the cafe, situated in the middle of the town, on Main Stree. Many years ago my father and uncle would 'fight' over cakes they bought in a wee bakery, situated where Asda is now. 'Diamond' cakes seemed to be their favourite
