Here are a few cultural ideas http://www.independent.ie/lifestyle/travel/inside-ireland/take-10-old-dublin-pubs-26523902.html
Temple Bar is an area moreso for tourists, worth a walkabout, but if you want to settle down for a nice pint, go where the locals go eg Stags Head, Kehoes, Grogans, Long Haul etc.
For food try Fade Street Social on Fade Street, decent pubs and restaurants all around that area of William Street/Clarendon Street/Drury Street/Georges Street. Best to walk around a bit as it is all very close together.
Head up to Camden Street/Wexford Street for later at night, or Bruxelles has a late bar.
