Ramen only contains the chiles if you order one with a spice level. As far as actual ingredients, the default is noodles, broth, green onions, and pork. You can add corn, bamboo shoots, bean sprouts, mushrooms, tofu, etc. They usually cost $1 per add on.
They adjust their spice level with Chile powder and can add serano Chile's as a topping or you can add chile oil once your order arrives as a condiment. Otherwise the other ingredients aren't spicy
