The menus for food and drinks at Onno's Bar in Cabarete are since quite a long time in US$.
Last time when I checked, when the Dollar was on the street about 32 Pesos, they still calculated in the bar with 28.
One presidente at Onno's is 2 US$, so at this time they charged 56 Pesos.
Don't know how much they charge now in Pesos, I will check on saturday.
Tip: right between Onno's and Bario Latino is a little bar called "La Cosita". There you can get the beer and cuba libre much much cheaper.
