I'm yet to find one that is consistent.
I've had a couple of good ones at Toby's estate but in saying that the last time not so good as I received a 15ml ristretto when asking for an espresso.
Still to try C of T though.
Sadly for real espresso drinkers, just about all the focus is on milk drinks, ie; art, texture and fancy names, so a good old espresso can be difficult to come by.
