Moved to Rush last year and have to say I love it. The village is great and there is everything you need near by from shops, chemist to hardwares etc..
Food wise - theres no real restaurants as such - but you can easily get a carvery in any of the pubs, There's also an Italian (yet to visit but has been recomended) and there's an Indian Restaurant. If their take away is anything to go by I'd say their restaurant is brilliant. Always packed on a Sat too.. Harbour Bar also do very reasonable food.
To be honest the local pubs (there are a few of them) wouldnt interest me for a night out but thats a personal choice of local pub. However Skerries is literally only 5 mins up the road with all those amenities, and I have to say Im more than happy to drive 5-10 mins to have food/drink at the harbour in Skerries. Actually same can be said for a night out. Blue bar in skerries is very good for both options.
I've lived in the City center, Santry and Artane for several years and this is far the nicest area. Beach (choice of 2) is only 5 mins from the house. The biggest change I noticed is everyone is really nice. It's a very samll thing - but people actually say hello to you. Shop assistants are always really nice. Maybe its a rural thing? I don't know. nice/Good service will always have a lasting impression and we've already got to know local people through their shops etc..and conversations.
The big DOWN SIDE is the train station! parking is a nightmare. Too far to walk and too dangerous to cycle (IMO) But the road is getting an upgrade and apparently a cycle lane - i dont know where? need to be there before 7.30 to assure yourself a spot. I've changed my work hours to 8-4.30. Drive to the station in less than 10 mins. catch the 7.15 train. In work at my desk before 8am. usually home just afer 5 allowing me to enjoy the evening and the beaches.
Swords is also only about 15-20 mins drive away if you need to do a supermarket shop etc..or have a larger choice of pubs shops bars etc..
PLus - I used to visit friends in Rush and used to think it was miles out - not anymore. Only 45 mins into town. usually get the port tunnel home on a sat and it cuts about 15 mins of that time. well woth it. For a night out in town you also have the nite link which services rush. usually takes abouit 30mins from town.
If you are looking long term and family wise (which we just started) there are also really good facilities. Local healthe center is brand new and great. Again local health nurse was a god send during the first few weeks of our baby arriving. People in the Chemist (Hickeys) are laso very helpfull.
New irish school is due to start in September and we just enrolled our little one in a local 'brand new' creshe 10 mins from the house. I think it will be a lovely place to bring up Children.
I cant think of any majoy negatives - unless you count getting stuck behind a tractor at 7.10 when you're trying to catch the 7.15 train
Sorry big long response but hope it helps.
