Ah, I so get you!!
You get to hear quite often that Starbucks coffee is not good or that it's simply not worth its price... but for me it's like the whole experience. Going there, chilling for a bit, reading a book, just sitting there to enjoy your coffee. It's a whole other thing rather than just coffee and, as you said, there's no special ingredients lol
someone gets me hhahaha
It's really not rocket science to make those coffee but it's the ambience that wins over us!
