Mannie Gianopolis founded his namesake dining establishment and ran it until retirement when it was taken over by his nephew and Joseph Koury. Koury took over more of the business gradually until he became the sole owner in 1985. Since then, a number of Koury family members have continued to serve guests. Homemade muffins, huevos rancheros, and burritos highlight the breakfast selections. Oversized sandwiches and fresh-cut chicken fried steaks are favorites for lunch and dinner. They make specials daily and are noted for homemade soups, especially the green chile chicken. Not far from UNM, Mannie's has many college customers who remark, "This was my parent's favorite restaurant too. Breakfast, lunch, and dinner.
