I had a noonday snack and spent more time in line than eating. There was an additional line to the restroom. Patrons got a single-use voucher with purchase, others paid half a euro. I suppose, due to the location near the monument, the facility would be overwhelmed if the restroom were free. I saw no waiters. The café appeared clean and the food was good. Prices were reasonable. An ATM was conveniently located inside the café.
