Rising Sun on Pondtail Road used to be okay but is a fair few years since I was last there. Used to have a proper old bar billiards table in there.
Still has AFAIK, so does the Stout House.
The Crown is worth a look from time to time, as is Piries and B52s.
Also the Queens Head has slightly improved in recent years.
Basically any town centre pub is OK these days.
