许留山 - Hui Lau Shan - non mango snacks are equally good!

This dessert shop is synonymous with mango desserts but for people like me who are allergic to mango, you will be happy to know that there are other dessert options which are equally delicious.
Try my favorite watermelon aloe jelly drink next time and you'll know exactly what I mean. It is my favorite drink and I have to have it at least once a week whenever I'm in HK. Pair it off with the signature XO carrot cake - you will love the spicy fragrant delight, especially if you like tasty scallop shreds in your crispy pan fried carrot cake!
