Cash Helps in Buenos Aires

Cash exchange is everywhere (Palermo especially). One weird detail: some places offered different rates depending on which U.S. bills you had — not all denominations were treated equally. You can pay for most things without pesos, but we regularly saw about 10% higher pricing when paying by card or Apple Pay. Small grocery shops liked cash, taxis were easiest with cash, and a few restaurants preferred it too. **Do this:** Bring some USD in mixed denominations and keep cash handy.
