My wife has a medium-to-mild case of lactose intolerance. She gets a bit gassy and bloated for a day or two afterward if dairy is eaten - which is not good if we're supposed to be on vacation and relaxing.
We'll be in Buenos Aires, Iguazu, and the Northwest. Are Argentinian waiters and chefs (especially in BsAs) accommodating to tourists with these issues? Will we be laughed out of a steakhouse if we ask them not to cook with butter? Are there empanadas down there with no cheeses and butter? I was hoping that the Andean northwest would be a little bit less cheese-crazy than their Italian-immigrant brethren down in the city.
