General Info
Wikitravel
Lonely Planet-Lonely Planet was an indispensable resource this semester providing everything from basic information, restaurants, bars/clubs, and things to do.
Frommer's- like Lonely Planet
Landing Pad- lots of funny commentary and insider info on BA, including things to do
Time Out- includes everything from things to do, places to eat, and places to go out. We used it mostly for bars/clubs. More local than Lonely Planet or Frommer's
Things to do
Trip Advisor
Restaurants
Guía Oleo-very specifice searches for restaurants by neighborhood, cuisine, price, delivery, you name it
Buenos Aires Delivery- just about everything is available for delivery in BA. This site makes it even easier.
Bars/Clubs
Happy drunk fest- hilarious blog of bars and happy hours in BA
Guía Epicúreo-bars by neighborhood, price, and rating
Hostels
Hostel World- has lots of ratings and all the information on hostels across Argentina.
