Is it possible to zoom out in Safari on iPad 2?
It sounds to me like your only option will be to have the webpage redesigned a little. Chances are there are some CSS styles that are sending parts of the text off the screen.

For the site, sometimes they include a meta "viewport" tag, which could be causing some problems for you. If this is the case, they should be able to easily remove this tag. However, it is very likely this is not causing the problem.

You could also request they use a media query to make adjustments based off of your iPad. This often works very well for mobile devices.
