Directly, not many places. Through gift cards. Absolute fucktons of places. I have been purchasing my groceries with Monero for over a year now, every single month, and bought some home insulation with Monero, and bought Thanksgiving dinner from a restaurant with Monero as well.

Edit: i also pay my phone bill with Monero

Edit 2: Truly, the only thing I have not figured out how to pay with Monero is direct debits, such as car payments, mortgage payments, etc. that require a bank and routing number. Anything payable with a credit or debit card is fair game.
