Niagara Falls/Niagara on the Lake

Hi there:

We are heading to Niagara on the Lake for a conference the last week in Sept with an extra day planned for pleasure. We are trying to decide whether we should stay at Niagara on the Lake or at Niagara Falls. We will spend time in both places and I would love some suggestions for places to eat. We like all different kinds of foods and we prefer places that are moderately priced and not super fancy.

Your suggestions would be greatly appreciated!
