La Pebeta is the first farm-to-table experience in Buenos Aires in Los Cardales. It takes under an hour to get here from Buenos Aires. This is a self sustaining farm and everything is straight from the garden to the table. What they don't serve at the restaurant they can or use as feed for their livestock.
Their menu changes weekly according to what they harvest and what's in season. Check their Instagram for menu updates. While it's not vegetarian, they do have vegetarian dishes and have vegan and gluten free options.
The restaurant is only open Thursday through Sunday for lunch. Visits on Friday, Saturdays, and Sundays include a tour of the farm.
Definitely make a reservation in advance via the Meitre software on their website.
