Macao was my first taste of Portuguese-influenced architecture - mind you this was back in 2003 - so in that sense, I liked it. There were barely any crowds near Largo do Senado (the main square)...but that could've been due to the SARS epidemic all the same. Egg tarts did it well too.
But now it's just an unpleasant, even more crowded place to visit. Not to mention, I have ZERO interest in casinos/casino "entertainment"/shopping. Egg tarts though, they still do it well.
