we took a cab to the A-Ma Temple (from which Macao/Macau gets its name) from the old center and man are cabs hard to find. there is a taxi stand located near the base of the hill where the fortress and Ruins of St. Paul are, but there are no cabs there.
protip: if you’re heading to the Venetian after this, take public bus MT4 (MOP/HKD 4.20 per person, exact change) which departs from the stop to the right (facing the street) of the temple. (in general, though, use the free casino shuttle buses to your advantage, especially after arriving and on your way off the island. for example, the Grand Lisboa shuttle bus from the Macau ferry terminal will take you very close to the old center.)
oh, another protip: there are SIM cards sold in vending machines at the Macao ferry terminal, but if you decide to brave it with wifi, there is a pretty decent free network called WiFi Go located at all the major tourist attractions.
sidebar A Lorcha just up the street on the right from the temple has some excellent Portuguese/Macanese food. in fact, it’s better than the food we remember eating in Portugal! wifi password is the long number written on a sign at the bar.
