Wireless router distance

[Mr. tech]

We currently have a wireless router at home which only can be accessed within about 20-30 metres... That's pretty dodgey.

Our office is now located in an area that has a coffee shop about 300 metres away. We want to be able to access our network wirelessly from there.

Are there wireless routers/modems that will reach that far? If yes, what do you recommend?

wow thats really far, wireless n, the best consumer level solution out there, only does 100m

Cantenna?

If you can connect from the coffee shop, so can everyone else at the coffee shop. Is that worth the risk?
