On the main road from Sanda south to Tabanan and at the same turn-off as Cempaka Belimbing, the remote roadside cafe Belimbing Café (Starfruit Café), Jl. Raya Belimbing (no phone; main courses Rp25,000; no credit cards; daily 8am-9pm), is owned by the same good folk that own the popular Café Batu Jimbar in Sanur. The view is spectacular. The extensive menu has many pasta and Indonesian dishes and does them very well. It makes an excellent lunch stop on the way north or south. Look out for their puddings.
If you could bottle a view, then Café Jatiluwih, Jatiluwih (tel. 0361/815245; sandwiches and main courses starting at Rp10,000; no credit cards; daily 9am-5pm), would be serving the most exquisite dish in town. They have soto ayam at Rp12,000 and a selection of sandwiches. The whole affair is aimed at the tourist market. It's worth stopping, having some local coffee, and just taking in the view.
