Hello @imanthadd96
Welcome to the community.
Your experience with your girlfriend at that coffee shop is nice and sweet. I like that you both shared each other's coffee to compensate for the bitterness of your cappuccino. There are so many things that might cause coffee to taste bitter, whether it's the brewing method, the equipment that needs cleaning, the state of the coffee, and many other things. As well as it could because it was just your first time tasting such coffee.
