Pretzel stores typically prepare and serve pretzels for immediate consumption. They may also sell nonalcoholic beverages and other related products, such as hot dogs wrapped in pretzel dough. The pretzel industry continues to make gains due to a demand for healthy convenience foods. The introduction of gluten-free pretzels and other specialty varieties has also boosted revenue. Pretzels are so popular that a large percentage of Americans consume at least one pretzel daily, on average.
