So this is just your run off the mill Starbucks as far as I could tell. This was my first Starbucks stop since starting keto and let's just say I definitely confused the barista.
If you want a low carb chai tea latte, you can order:
Short Chai Tea Latte using 2 Chai brewed tea bags, 2 shots heavy whipping cream, and 2 pumps sugar-free cinnamon dolce. 206 calories, 4g net carbs, 1g protein, 22g fat.
If you want it to be an iced chai, apparently it needs to be a tall, not a short. This Starbucks also doesn't do pumps if heavy whipping cream, but another barista said that was just a normal pour.
They were very accommodating and my barista even double checked after I got my order to make sure they got it right. I definitely appreciated them accommodating such a custom order!
