Looking at their Facebook page, Dionisos Wine Bar and Restaurant in Lima with its comfy chairs and dim lights has the feel of a club.
I could not gather much information from their website as it seems you need to be a member (with login) to check the wine of the month (vino del mes) and the wine list.
An article by Sophie Kevany in April 2009 right after Dionisos opened tells us that 32 local and international wines by the glass and 450 by the bottle were offered.
Some more details offered by Sophie:
plus a corkage fee of 25 to 35 Peruvian soles (€5-7), to encourage
drinkers.
The bar offers different sized pours ranging from a two ounce
tasting glass, to a 15 ounce flask, as well as flights of single
varietals grown in different regions, or the same vintage from four
different countries.
It also features a wall of pisco, a grape-based brandy and
Peru's national drink."
