We've dined at Raglan Road several times over the past couple of years and have always had good experiences - good service and food and we go a little later in the evening so we can enjoy the Irish folk band (they don't play on Sundays). As someone else stated, you will get a variety of responses from people here but we've had nothing but good times at Raglan Road.
They have a good selection of beers on tap and offer four different beer flights; they also have a good selection of Irish whisky and single malt scotch - they offer flights for these as well.
We like the Dalkey Duo for an appetizer (deep fried little sausages) but have also heard that the Scallop Forest is tasty.
Various entrees we've tried over the years ... fish & chips, heavenly ham, shephards pie, guinness beef stew ... they have all been very tasty.
and save room for the Bread and Butter pudding - the hubby and I usually split it because it's a big, rich portion ... and it comes with butterscotch and creme anglaise sauces to pour into it.
