Robert's linked review is AWESOME but since we were just there on Sunday & had completely different items off of the menu I'd like to add our experiences:
We had 6PM reservations but after waiting for a half hour for the bus we knew we weren't going to make it in time. I called RR, they resceduled us for 6:30 without a problem and we were seated immediately when we arrived (it turned out that the DTD bus had broken down en route to us).
We found the bread to be good, but very hearty. If you're planning on a heavier entree you probably won't want to fill up on the bread but definitely try it. The guinness reduction that they served to dip it in was a nice, sweet touch.
We had the fried calamari appetizer and it was lovely. Very, very light batter and perfectly crisp tempura veggies. My son ate most of the calamari

.
My husband had the four provinces flight which is a great way to try out any beer that you're unfamiliar with without committing to a full pint. My husband was very familiar with all of the beer offered

. Still, he couldn't make up his mind so the flights are a good idea.
The one beer that he hadn't had before was the Tucher Hefe Weizen so he ordered a pint of that. The fact that the pint arrived garnished with an orange slice should have tipped us off. Be advised that the Tucher is a very, very fruity beer & not the best choice for drinking along with food (or at all

).
Anyway, my husband had the mixed grill which he really enjoyed but I NEED to tell you that the Salmon of Knowledge is TO DIE FOR! Oh I've been going nuts trying to get the recipe ever since we got back. It was perfectly cooked, perfectly moist and just divine. The smoked salmon across the top provided just the right amount of saltiness and the glaze just the right amount of sweet. If you like salmon, please try it. It comes on a bed of mashed potatoes and sauteed leeks, which was also good but, oh, the salmon!
My son had the chicken & chips. Very heavy batter on the chicken, like you would expect to find on fish.
For dessert my husband had the bailey's creme brullee (served as a pie slice rather than in a ramekin) which was delicious but a bit sweet and I had the chocolate trio (dark chocolate mousse, white chocolate mousse and a small chocolate shake...really, is there such a thing as too much chocolate?). The dark chocolate mousse was very rich, the white almost like froth in comparison and the shake was good, but just a shake. If I ever do go back I'll have something else for dessert. I was afraid that the bread pudding would be too heavy.
We live & work in close proximity to large Irish communites with many of these Irish pub & nouveau pub style restaurants. We're also just north of NYC with it's many outstanding Irish & English restaurants so the food was nothing new to us but I would go back to Raglan Road in a heartbeat. I'm already on the hunt for the chef's cookbook.
