Completely agree on Mighty Taco....it's one thing if your a former WNYer returning home looking for some Nostalgia but for someone coming from out of the area that's never been before there are sooooo many better places you can get food at and we have so many better Mexican places now than we have ever had in the past. Don't waste a meal on Mighty
If your a sports memorabilia/Bills historian kinda guy try to find some time to make it out to the Eastern Hills Mall, there's a bunch of sports collectible and flea market kinda places with a lot of cool Bills and WNY stuff in there and then Dave & Adams is a massive sports card and memorabilia place right outside of the mall. You can also get Bills gear both new and vintage stuff.
