Best option to get Pesos with credit card in Mexico?

HSBC also has branches thoughout Mexico.

Watch out for ATMs esp those not at banks. There has been a scam where the machines were fitted with a chip that scanned and stored info which was later downloated by the scammers via a bluetooth connection. Use your smart phone to check for a bluetooth connection at the machine and if it shows one, DON'T use that machine.
