Some places in the east have marble rye... I love when they offer me a bagel as a substitute
such as at Johnnie's Luncheonette in Newton, Mass.
I adore raisin toast, Sunmaid is the best. Sourdough toast when I am back in CA too, Columbo's sliced makes awesome toast. Some of the "gourmet" breads there make great toast too, like potato rosemary.
All this year I have been eating British bread (sliced supermarket stuff's way better than it's American "equal").. I get the malted & seeded loaf and have it the British way with both butter AND peanut butter. Yummy!
