Great Food, All the Time Jalapeno Grill is a family-owned restaurant in Wilmington, DE. After coming to California in 1997, we started working with our traditional recipes for the joy of our family and friends. Real Mexican food is all about the freshest ingredients and the love you put in your recipes as our grandma taught us. That’s why our ingredients are freshly picked daily, and our top-quality meats are marinated in house to perfection.
