Nothing much around Nusa Dua besides other 5 star resorts...
Taxis in Bali are super-cheap anyway - a taxi from the Sofitel to Kuta will cost you about US$10, just make sure they put the meter on. Bluebird taxis are usually reliable, see

Alternatively for around US$50 you can get a driver to take you anywhere around Bali for the whole day.
