What city has the best "restaurant community"?

I’d give it at least a B+. When Saveur did their first issue singling a city back in 2007 and their restaurants and cuisines, they picked Chicago(land), so we got that going for it. (A slice of Burt Katz’s [RIP] pizza from Burt’s Place in Morton Grove was the cover, with the headline " Chicago! From delectable deep dish pizza to cutting-edge restaurants, discover why the Windy City is America’s new culinary star")

I wouldn’t quite put it at A tier overall, but for certain cuisines, it fits the bill.
