Agua con o sin gas. Water, with or without carbonation. In a bottle, and not from a tap. This is a good thing.

Asado. Grilled meats, available everywhere and served as a variety of cuts including organ meats you cannot name.
Café con leche. Espresso with hot milk. A dietary staple.
Casa de Te. House of Tea, although this is unlikely to be true in any aesthetic sense. If they own a teabag it is casa de te.

Parrilla. Grill. A place that serves asado, meaning practically any place with sit-down service and a waiter.
Pan. Bread. Panaderia. Bakery. You can open a store that sells anything by adding –eria to the end of the thing you sell. A ferreteria, for example, sells ferrets, although they apparently also sell hardware.
Pollo. Chicken. Grilled, or used to fill empanadas.
Salado. Technically salty, but apparently anything not sweet.
