First, the history. Renaissance Bakery, which has scored a bunch of awards from us in the past several years for its outstanding sourdough, olive, and sesame-semolina loaves, was founded by Ron Funt. Now, the present. Funt, along with brother Paul, decided to put Renaissance bread to even better use than selling it out of the back of the bakery and transporting wholesale orders to local restaurants and markets. They opened Upper Crust about a year ago, doing the chic décor -- lots of chrome, glass, stone, and marble -- themselves. So take the name literally. The appearance of this sandwich shop is literally a cut of bread above the rest, as is the Renaissance Bakery itself. The sandwiches are, too, giving a new meaning to portable lunch. Peanut butter and jelly, which is smoothed between two slices of raisin-currant-pecan bread, never had it so good. Now, there really is something better than sliced bread.
