Hi in my 30+ years I've never been to a Costa coffee. I'm going with my friend on Saturday for a chat and a catch up. I don't drink coffee I like fruity teas though. I've looked online at menus and the mango tea sounds nice but then it popped up with secret menus and things and I got confused and overwhelmed (I like to plan in advance what I want to order) what would you recommend to a Costa newbie.
