This afternoon we had coffee at the outdoor cafe behind Reunification Palace, Cafe 30/4. A great location, although the marble stools, polished smooth by customers squirming uncomfortably, could have done with some cushions. They do have real chairs which I'll be using next visit.
We bought some fruit from a local trader, and found out from one of our security guys that it's called lý (and aka, according to the interweb, rose apple). He 'opened' one for us by applying pressure until it popped open. Lovely tasting fruit, a slight musky/rose flavour, with the texture similar to a pear.
