Greyhound Racing: How many ways can you gamble in Macau?
Apart from casinos and the horse races, there's the greyhound races - the only one in China that allows people to bet on dogs. I haven't been to a race myself as still unsure if it's ethical with conflicting reports on how the animals are treated. The stadium is clean and spacious, and this, their logo is fabulous - reminds me of the london olympics 2012 logo.
The neighbourhood itself is very local and filled with interesting architecture.
I would recommend a look, and leave it up to you if you'd like to watch the race. Wednesdays and Fridays are off days for the race.
