if by "good" you mean good for you, then no. but most people like it. it's kinda like hot chocolate, only with other flavors like caramel and vanilla. it's WAY to sweet for me. i like strong, black coffee, but if you like sweet stuff, you will like cappuccino.
Cappuccino is one of the best ways to dribk real good coffee, dont ask for it at starbucks, that is baaad coffee. It is espresso coffee with steamed milk. This milk caramelizes a bit and takes flavot a bit like condensed milk and balances well the punch of the espresso. Taste a bit like heaven and daaamn i want one right now
