Cagliari is known as "The City of Sun", so you must have a full relaxing day on the wonderful Poetto Beach. This 8 kilometers long beach will excite you and is perfectly equipped to satisfy every your wish. You can get here by buses PF,PQ,3P,9P.
The beach is divided to free parts and 'beach clubs' that charge you with entry fee and rent you umbrellas, deck chairs etc. Prices are around €3 / entry, about €12 for a umbrella, one deck chair and one sun bed. The 'club beaches' clean the sand each night and provide you with showers and toilets too.
Most of the shops are concentrated in a couple of areas: Via Roma and Largo Carlo Felice, the pedestrial roads Via Manno and Via Garibaldi, and the part of town around Via Alghero, Via Paoli and Via Dante. Lots of beautiful shop are concentrated in this areas which could remind you of Copenhagen's Strøget.
There's a LOT of restaurants in the old town area, and you probably will not make a bad selection anyway since the food seems to be top class at least if you enjoy seafood. A dinner for two with little house wine, There's a good pizza place tucked away in the side streets in the Marina district, l'Oca Bianca. You should make a reservation, though.
There's a few places to enjoy lunch salads at the Piazza Yenne, and a wonderful Gelateria if you don't want to eat too heavily during the day. These places double up as decent eateries by night.
