We checked out the Harp and Crown with some friends last night and had a great experience. Note that it is on the small side--not a lot of tables, but they do accept reservations. It was a full house (Friday evening around 6:30), but thanks to a little planning our party of 6 didn't have to wait for a table.
There are some unique cocktails offered on their drink menu (a version of a Russian mule, peachatini, cheeky monkey, etc.), and also a great beer selection.
We started off with the curry chips based on reviews here and they were as good as reported! We also tried their spring rolls that are filled with corned beef and cabbage with a great mustard sauce and they were also really good.
The issues with their fish and chips must have been resolved because they were really good last night. We tried several of their burgers (Mr. Bean was excellent) and the Paddy Pacino (very good although the burger was a little overdone, definitely not cooked to medium). You can also ask for a side of their curry sauce for dipping your chips--it is a delicious treat. The salads are a little pricey for the size of the serving (particularly for the meal-sized salad), but it was still good flavor-wise. The Guiness-braised brisket was delicious, although the size of the meat looked more like what you'd see at a "fancy" restaurant than what we expected from a pub.
Overall we really liked the Harp and Crown. I agree that they need a POS system because the hand written bills seemed a little clumsy. The service was also good, but a little on the slow side (a POS system could help improve that). We will definitely go back.
