moderate-priced favorites in Dublin
for cheap ethnics, Parnell Street is the place to go. Allilang is one of my favourites here for dirt cheap Korean food.
A good site to research a few restaurants on is www.menupages.ie which includes menus and prices for most city centre restaurants in Dublin- it also includes user reviews.
For lunches, I would recommend avoca cafe (Nassau Street), epicurean centre (Abbey Street), cornicopia (Wicklow Street), Queen of Tarts (Dame Street), Lemon creperie (Dawson Street)
