Little Angel Coffee is located in the Perth CBD and liquid nitrogen is their main game. We're talking pandan and coconut nitro gelato affogato and all sorts of crazy flavours which change each month so you never get bored. They've also got some of the most delicious looking baked goodies available. But, fear not health freaks, they also dabble in a healthier range of foods to please you too. Head down to Exchange Plaza, stat!
