The Coffee Bean and Tea Leaf
Though it's most well known in California, The Coffee Bean and Tea Leaf has locations across the US, and its pumpkin spice latte is not one to be missed. The coffee shop specializes in a french vanilla powder that sets this pumpkin spice latte apart; you get strong notes of nutmeg and cloves along with the sweetness of the vanilla. That said, this latte is really sweet and might be too sugary for some.
Pro tip: Order it with almond milk even if you're not dairy free. The nuttiness of the almond milk rounds out the sweetness and enhances the flavors of the pumpkin and spices even more.
