Ah, Caffe Florian. I’ve been there.
Founded in 1720, it’s said to the world’s oldest cafe, though others disagree (generally those who’d like to claim the title, I suspect). Apparently it was popular in its early years because it was the only coffee house in Venice to admit women. I slightly feel like not excluding half the population would be a pretty good way to be popular anyway. But maybe that’s just me. *Insert tea-sipping Kermit here.*
That said, the activity that goes on in this chapter - specifically, moving all the tables to stay in the shadow of the Campanile - is completely fictional. The Caffe gets a specific area of San Marco Square they’re allowed to use, and they’re just not allowed to wander around. Also, the sitting area is pretty much in the shade of the building along the south side of the square anyway.
Aria, page 150… think you’ve got enough sugar in that hot milk? (Although, since the waiter is presumably listing the drinks in the order he’s serving them, and he’s clearly put Aria’s drink down first, perhaps Aria has the latte and Akari has the hot milk?)
Page 156, some small drawing issues here - specifically, Aria’s teacup has the same design as Akari’s when it’s on his head, before it turns back into his own cup on the following page. Though, how he reached up to his head with those tiny arms is beyond me. Maybe he used his tongue. 
Think I’d hesistate to use the word 英雄 in reference to Napoleon.
What on Earth happened to Akari’s face on page 170?
Page 175 is he calling Akari the expert of happiness, or himself?
@Naphthalene Oh, you’ve read it already. So, small query: page 162 in the Masterpiece volume, the first narration box reads このカフェ・フロリアンは今から５８０年ほど前に (emphasis mine). However, the Tokyopop translation says “Caffe Florian was founded in Venice on Manhome about 435 years ago.” What age does your copy give?
