The Wig and Pen is a lovely pub situated not far from Swansea waterfront and University. It has good access for public transport, is a quick walk away from town and Wind Street and/or the beach and also has public parking (not their own car park) very nearby.
They offer a choice a standard pub meals that are always cooked lovely, the décor is clean and fairly minimalist since their refurbishment not so long ago, they stock all your usual favourite drinks and allow your pooch to accompany you inside. They also offer live music some evenings.
Would definitely recommend if ever you are in the area.
