Horrible service and extremely rude waitress. This was the 3rd time we had gone to the Harp (specifically for the live music) and it is nearly impossible to get a drink (even though the times we have gone the place was virtually empty.) Good beer and decent food, but again the wait staff just killed any potential this place had. A woman working the patio last night was especially rude and very slow.
I wish that they would hire better (and more) people. Our friends who recommended this place to us because of the live bands told us "Oh yeah, the service here is TERRIBLE and they are always really rude but we come here once in a while because sometimes the bands are good."
