Ok, here is my choice, waypoints maye not be 100% as Mapsource doesn't have specific eateries listed, but here goes:-
1. The Galley, Glassdrumman Rd, Annalong, Co Down.
N54 06.612 W5 53.969
Take away only, but weather permitting tables outside. Best choice of fish I have ever had, size and variety.
2. Mortons Fish Shop, Ballycastle Harbour, Co Antrim.
N55 12.443 W6 14.454
Co Antrims answer to The Galley. Again take away only, can wait for your fish but choice, variety, size and quality worth it.
3. The Pitstop, Balloo Rd, Bangor, Co Down.
N54 38.355 W5 40.125
Choice of Take away, roadside trucker type set up or sit-in and enjoy huge variety, from Ulster fry to Sunday dinner, and pots of tea/coffee, very reasonably priced and large portions.
4. Cafollas, Conway Square, Newtownards.
N54 35.588 W5 41.773
Small family run diner, sit in or take away, everything from beans on toast to Ulster fry and fish and chips and the famed Cafollas Ice Cream. Get there on Saturday and avail of the street market being overwatched by the bronze statue of Blair Mayne.
5. Daft Eddies, Sketerick Island, Co Down.
N54 29.287 W5 38.896
Bar/Lounge/Restaurant overlooking Whiterock Bay and the yacht club. Outside tables are a favourite in the dry weather.
6. Herrons Country Fried Chicken, Bridge St, Comber, Co Down.
N54 33.072 W5 44.551
Personal favourite and very tasty better, (we think) alternative to KFC. Take away only but Kebab on chips with chicken gravy sauce to die for. (Not real kebab meat, just fried chicken diced, but Mmmmmm)
7. AJ's Downpatrick Rd, Crossgar, Co Down.
N54 23.748 W5 45.637
Just agreeing with Geno here and adding waypoint. Top Nosh.
Sorry if the waypoints are not 100%, but if you get that close you'll see them. Think thats enough for me for today, beginning to look like advertising section in Yellow Pages, hope they have been a help.
