If I order a caffè latte from a coffee shop, will it always be the same strength? As in the same ratio of espresso to milk? For example, I think I heard that Starbucks UK use more espresso than is normal, though I can't remember if that's compared to "normal for a latte" or the other Starbuckses in the rest of the world.
Or does it vary wildly from shop to shop (and thus I need to learn or ask at each individual coffee shop)?
