Just came back from Macau 1 week ago. Was staying at Venetian Hotel. Its 1 of the convenience hotel that provide free shuttle bus to several locations. There is hardly any requirement to take cab in Macau.
For food wise, i went to 'Guan Ye Jie'. Its somehow an old food street where you can get cheaper food, there are restaurants too.
You can do a search for Seng Cheong, they sell famous crab roe porridge.
THe other 1 i went to was Dumbo restaurant. Nice food and ambience too.
Price wise is about SG restaurant price.
Anyway don't expect food to be cheap there.. was shioked when i saw the prices in Venetian food court.. mainly HKD50 to HKD100 per plate.
