Translation of walnut in Spanish

We agreed to stay in the room with no windows and unpacked our bags. We wanted to have dinner and went out to a Sushi restaurant a friend told us about. It was a great place with great atmosphere.
Do you want learn Spanish? Do you have a telephone? I am looking forward to hearing from you and sorry again, I was extremely busy during the last three weeks. I hope you can forgive me.
Than we took a cab to the actual border crossing. In the cab we took gave a ride to another tourist and with some scary Peruvian guy, who had a bag full of faked CDs. He didn't seem too nice and had many scarves.
