my family will be driving up to niagara falls and toronto this summer, and while we have a rough outline of our itinerary as is, we're flexible and i'd like to solicit recommendations and information for our trip.

1. driving up
i understand that we should be fine driving up through NY with our passports, US-issued drivers licenses, and proof of insurance. but i welcome any tips for crossing north or coming back. is it better to cross in buffalo, on the rainbow bridge, or lewiston?

2. restaurants
we are particularly interested in toronto's chinatown, or any notable ethnic food. we are staying at the delta toronto/downtown area.

3. kid friendly
any out of the ordinary kid-friendly venues or attractions - for middle school aged kids? we've got plans for activities around the falls, the cn tower, ripley's aquarium, great wolf (they love magiquest), and a few others. someone once mentioned to me that there is good waterskiing in niagara somewhere around niagara-on-the-lake, but i have no other information.

i know there are some hockey-themed places, but we have no interest.

i appreciate any input. thanks!
