One among the best cafes of Thessaloniki with "proper" frappe, nice view and great atmosphere.Still not sure, but can suggest from experience that greek cafes serve sweets with frappe only in winter time. In Αχιλλειον cafe frappe is served with shortbreads, which go really nice. 
As about frappe there're no comments... nice and smooth... satisfied completely.
Waitress, by the rules of serving, did her best. And as a human was quite welcoming.
And that what i want to suggest you. Visit Αχιλλειον cafe when you are in Thessaloniki. No regrets for that. And please, i need comments from those who visited cafe already.
ΑΧΙΛΛΕΙΟΝ cafe, Λεωφόρος Νίκης 37
