When you are downtown in San Luis and you walk past the House of Bread, you can't help but walk in. The smell from outside is wonderful and they even have a huge fan outside that I am sure is meant to circulate the aroma of freshly baked bread. They have tons of varieties of bread and they also have special breads that they rotate daily. In addition to loaves of bread, they also sell muffins and scones. They offer free samples, so you can try the breads out before buying them. The best thing there is the low-fat cinnamon peach muffins - they are wonderful!
