PREFACE:
This could probably be a whole essay but I'll try to be concise. Many people go to cafes and most of them order the same handful of menu items without really understanding what exactly it is they're ordering or why. You might be one of these people and that's ok! You don't have to be knowledgeable about every little nice thing you enjoy consuming.
However, many of the very popular drinks you'd traditionally find in most cafes are not particularly good for one reason or another and as a barista I think that 9 times out of 10 you're better off ordering something else instead. In this thread I'll go over some traditional drinks that I particularly dislike, explain why I think you shouldn't order them or why you might not be able to even find them in specialty cafes and I'll suggest better alternatives that scratch similar itches.
Please remember these are my (fairly educated) opinions and not absolute objective facts. If you absolutely love one of the drinks mentioned below and you've already tried everything else and none of it works for you that's completely valid. My goal here is simply to educate, clear up some misconceptions and, hopefully, guide people towards finding more enjoyable coffee experiences. WITH ALL THIS SAID:
