It's a two-hander bottle they give you to pour for yourselves
at Alla Vecchia Bettola in the wonderful San Frediano neighborhood, a 25 minute walk from Santa Croce.
When the meal is finished, they eyeball what's left and charge accordingly.
The food here is all you would hope for from Nonna,
served unpretentiously, to almost exclusively
local, ardent patrons from the neighborhood.
