Mei Hong Yuen Dessert, Chinatown
Since we were in Chinatown already anyway, we stopped here (65 Temple Street, 6221-1156) for dessert, a place that was incidentally featured in 8 Days this week for featuring Taiwanese "snow ice." They didn't have any mango flavor listed on the menu, but I couldn't imagine eating any other flavor of this stuff so fortunately we found out that it was indeed available as long as you asked for it.
And lo and behold this giant thing came out for only S$5 (US$3.30). I was surprised to find that it was all made from the tissue-like flavored stuff rather than sitting on a bed of shaved ice underneath, but that worked just fine for me as it was just what I needed to purge out all of that oil and salt from dinner. Just watch out for the brainfreeze.
