Chick and Ruth's & Cantler's = no way I would eat there again.
Try Osteria 177 on Main Street, not bad.
Since you will be in town on a Thursday - be sure to try the Turkey Sandwich at McGarvey's - @ $8.95 it is superb and not really a sandwich, more like a thanksgiving dinner. They roast a couple of birds on site every thursday. Be sure to be there on time because they tend to run out of turkey around 12:30 pm.
Reynold's tavern has got decent basic food.
Galway Bay for shepherd's pie and Guinness.
Davis' - for drinks, not food.
