You will have to wait at Mom's. After all, you're not the only one who wants to nab some of the best sandwiches in St. Louis. But you know what? You won't mind. The wait's brief -- five to ten minutes, max -- and allows time to study the uniformly tempting menu. Do you want a Ron's Special, with hot salami, pepper cheese and spicy mustard? Or a meatball sammy with homemade tomato sauce? No matter which sandwich you choose, it'll be made right in front of you, with fresh-baked bread and top-grade, locally sourced meats. At the register you'll get the best kind of sticker shock -- just $2.95 to $5.05 for your meal-and-a-half sandwich.
