Great practical question 👍 because tipping culture in Argentina (and especially Buenos Aires) is different from the US/Europe, and many travelers aren’t sure what’s polite or expected.
💰 Tipping in Buenos Aires #
Restaurants & Cafés #
- 
Expected, but modest. 
- 
Standard: 10% of the bill (in cash, even if you pay the bill by card). 
- 
Rounding up small café bills is also fine. 
- 
Example: Bill ARS 10,000 → leave ARS 1,000 tip. 
Bars #
- 
Not strictly expected, but rounding up or leaving a few hundred pesos is appreciated. 
Taxis / Rideshares (Uber, Cabify, Didi) #
- 
Not expected. 
- 
Locals usually round up to the nearest 500 or 1,000 pesos. 
- 
Apps don’t always make tipping easy, but a small extra cash tip is appreciated. 
Hotels #
- 
Porters: ARS 1,000–2,000 per bag. 
- 
Housekeeping: ARS 2,000–3,000 per night left in the room. 
- 
Concierge: Small tip if they secure hard-to-get reservations or tickets. 
Tour Guides / Excursions #
- 
Group tours: ARS 3,000–5,000 per person. 
- 
Private tours: 10% of the tour price. 
- 
Free walking tours: Expect to tip ARS 10,000–15,000 (≈ $10–15 USD at the tourist rate). 
Hairdressers / Spas #

About 10% of the service cost. 
✅ Quick Tips #
- 
Cash is king for tips — many places don’t allow tips on cards. 
- 
Locals tip less generously than in the US, but more consistently than in Europe. 
- 
Not tipping at all in restaurants is considered rude if service was good.
