Ely wine bar, (in CHQ) is nice, although a little pricey IMO. Second vote for harbourmaster, chicken wings there are the best in Dublin IMHO. Carion hotel is good too, Kudos is the restaurant, Asian food if I remember rightly, nice food though. Also, Lagoona is a bar there, they do nice food, not sure about evening time though, only usually around there for lunch.
As someone else suggested, try menupages.ie
you can do a search on this for location, so might find something else too.
