I think my cups are closer to 200 ml, which apparently is approaching 100 mg caffeine per cup, so I guess you're right.

A "medium-size coffeehouse coffee" (at Starbucks) is 16 fl.oz. Here in Europe, that's not really a normal cup of coffee.

America! What's a normal-sized coffee there, to compare? Large at Starbucks ("venti") is 20oz (~591ml). The caffeine levels at $ seem to be similar between USA and EU: http://www.caffeineinformer.com/the-complete-guide-to-starbu... but I'm guessing that that's more due to it being such a touristy place. From what I've seen, they use less espresso than "real" coffee shops: http://www.starbucks.co.uk/blog/introducing-our-new-standard... if you've paid attention to espresso machines for whatever reason, you know that most machines make two shots per pull, so typically higher-end places will use either 2 or 4 shots (since that's either 1 or 2 times they need to make espresso for the drink). If they have a large size (16-20oz), I've found that it's common to use 4 shots in that, which is going to be more caffeine than $, possibly by a wide margin.

If you're in the Bay Area and really want to go nuts with your caffeine for whatever reason, Dutch Bros in North Bay / East Bay (usually go there when I'm by Sac) has drinks on their menu with 6 shots: http://dutchbros.com/AboutUs/OurMenu and they're atypically strong per-shot.
