Ok a couple of ideas for NFO.

First off when visiting the wineries, try and find a local one. Some of them mentioned here Jackson Triggs, Inniskilin have been bought up by large corporate entities and are not like they were. In fact JT is connected to the old Bright's wines, total gutrot stuff (not saying they don't have good wines, just there are better).

Some of the more local wineries with restaurants (I believe these have restaurants) are Angel's Gate, Henry of Pelham, Joseph Estate, Pilleteri, Chateau de Charmes, Reif (I know these guys don't have a restaurant though).

For local restaurants, well in NOTL they are pretty much all tourist. The town may be considered quaint, but compared to when I grew up and used to head down there drinking in the 80's, it is a tourist trap as well, just a bit more upscale.

If you can take back some jams or preserves from Greaves - they have a retail store on Main St. NOTL. Not cheap but incredible quality. Just up from Greaves, same side of the street is a local restaurant (drawing a blank on the name) - last summer I believe the building was yellow - distinguishable by its large patio/front porch. It is close to the local theatre if that helps.

Now in Niagara Falls. There is no distinctive Canadian cuisine per se - it is like everywhere else in North America. Some of the local restaurants include:

Zappatelli's Pizza, Mick and Angelo's, Far East, The Bellevue Tavern (excellent wings, not sure kids are allowed though) and while touristy Falls Manor Broasted Chicken.

Now for activities. If there is snow, you can cross-country ski at Whirlpool Golf Course (on the parkway towards NOTL). You can also stop at the Horticultural Gardens, next to the Butterfly exhibit. The only museum worth going to was the Niagara Falls Museum but it has since closed down As has been suggested above, consider a tour of Fort George.

Oh yeah, when in NFO, go up the Skylon Tower. You will get an amazing view of the Falls and surrounding area. At night with the lights on is the best time, but your view of other things is somewhat limited.

Now if you were truly local, then you would head to Niagara Falls, NY for cheap beer and wings
