My recent visit to BA beg Feb 2020.
Easy and safe exchange at Florida at 73 pesos per USD.
Then a huge bife de lomo at London Steak House at Florida 800 pesos.
Then a bottle of Malbec there at 390 pesos.
Then a taxi from there to Plaza Dorrego (San Telmo) for 215 pesos (the driver received 250 pesos and thanked profoudly).
Who says it's not a bargain (for the time being, at least)? :-)

My previous visit, 2 years ago: the exchange rate at Florida was 17 pesos/$ and the prices in pesos were half of those quoted above.
