Shinagawa

Hie, I am going down to Shinagawa for a business trip for 2 weeks. This is my first trip to japan. I am wondering how much a meal would cost there? Is there anything i should know about the place?

IS there any interesting nearby place to visit there?

Shinagawa or Shinagawa Station area? Anycase meals range from expensive to cheap, just depends where you eat at. There should be plenty of places to find almost anywhere to eat there.

Great tempura restaurant in basement of Wing on hotel side of road: really authentic;
Sengaguji temple; Shinagawa Tokkaido Post road area; Happoen garden; Hatakayama collection of tea ceremony ceramics;
Ask at the concierge of your hotel: there have local maps with good walking ideas

The Shinagawa station area is like a lot of station area's in Tokyo, Lots of shops and restaurants in all quality levels and prices. It's a good place to discover other area's of Tokyo as the station is on the circle railway.
