Datsun,
Been living in Macau for nearly three and a half years now.
In terms of places to go and things to see:
For a bit of history/culture try Guia Hill, Senado square, A-ma temple, ruins of St. Pauls, taipa houses. The government's toursit website has useful information:
Macau Government Tourist Office
There is also a go-kart track, horse racing at the jockey club and even greyhounds at the canidrome.
A trip to Coloane island (the southern most of the 3 islands all linked by bridges that make up Macau) is worthwhile and there are good restaurants at the small beaches in Hac Sa (Fernandos) and Cheoc Van (Gondola). My favourite (although a bit rough and ready) is Nga Tim's which is outdoor in Coloane village near the Chapel of St. Francis Xavier (great seafood and bbq).
For a great feed in the evening, Aurora (Crown Hotel) and Copa Steakhouse (Sands Casino) are top of the range. In old taipa village, there is Petesquaria for great mid-priced Portuguese food and the local ex-pats pub (Old Taipa Tavern) is round the corner.
For night life there is the OTT and irish bar in Taipa and a nice bar in Aurora at Crown. Otherwise there are bars in the casinos like Lion Bar (MGM) which is currently popular or the bar strip in Macau by the water with places like MP3 and Moonwalkers. If you push on then DD2 in the AIA insurance building is popular at the weekend.
In terms of casinos, the new MGM in Macau and Venetian (between Taipa and Coloane) are both now open. Wynn's, Sands and the Grand Lisboa are also popular in Macau.
Not sure of the limits on blackjack tables as i don't gamble but usually there is a choice of areas with diferent minimum bets as low as HK$ 40.
I hope this helps!
