Never had them called that ... But, I have had 2 or 3 shots of espresso added to their large sized coffee before ...
I love espresso, but it's too expensive to drink a big 24oz+ mug every day, so Usually I stick with french press ... it's pretty much as concentrated as espresso, but much cheaper/easier to brew ....
On Fridays when I work from home, I drink 48 oz+ ... it's fantasticly delicious!
