The taste: The meat is very very tender, but a tad fatty; this is not diet food. The egg and mayonnaise add a richness (and greasiness) to the taste, keeping the cheese at bay, which would otherwise overwhelm the flavors. The tomatoes keep it from getting too heavy, but it's also important to know that the bread of the sandwich is the least important part.
The price: At a kiosk in the park? Expect to spend 17.50 ARS ($4). At a restaurant in an Argentine city? 35 ARS ($8) is a good going rate.
Where to find it: Just this week, we chewed our way through three different lomitos in these locations: a kiosk at the road border station in the Andes between Chile and Argentina, at a kiosk in Mendoza's Parque San Martin, and at Mendoza's La Aldea restaurant on Aristides Street. While lomitos are most popular in the wine producing Cuyo region of Argentina (of which Mendoza is major city), we've also found them all over Buenos Aires.
