I am attempting to write this in kana:

Mr. Smith ate lunch at a restaurant near the office.

So far, I have:

Sumisu-san wa resutoran de hiru-gohan o tabemashita.

I don't know where exactly to place the "near the office" (kaisha no chikai-is this correct?)

I am not even attempting to type this in kana here because, though I have the Japanese fonts installed, I have yet to learn how it use it. Sentence structure is still a little difficult for me to envision and create.
