If you don't feel like cutting the fruit itself, good news for you, you can find a lot of mangoes product all over Taiwan. Like mango ice cream for a start (which I bought from 7-11 so it's not expensive at all).

Or mango tart? I did not see this item when I came to Taiwan in winter so I think this item must be seasonal! Go get one from IJ Ysheng Bread Store (which are located all across Taipei, you will recognize it's purple signage).

And the yummiest of all especially when eaten on a hot summer day is of course, the ice mango (芒果冰/ mángguǒ bīng). This one I ate at Ximending. 

If you happen to be visiting Taiwan in summer, go eat the mangoes! Nom nom nom! =)
