Panera Bread has a good amount of what you're asking for, I think. Its a national chain of bakery and sandwich shops, known for their coffee as well. I really do enjoy going there and getting a bite from time to time, their bagels in the morning are stellar as well.
...But as for the whole pastry thing?
Its likely going to depend on where you are in the country to determine what kind of food will be available. California has far too diverse of a population to really get a good solid feel for whats out there, but go to places like Louisiana or even here in Michigan and you're likely to find something to love.
I know that at least here in the Mid-West, the Meijer chain stores have an excellent bakery in every one and sell exactly what you're looking for...
