Owners Crystal and Marguerite have deep ties to the railroad. Their family does too, including the Rock Island Lines. Hence the name. Their take on Mexican food is rooted in their family too. Street tacos, appetizers, tortas (sandwiches), and salads are some of the options on their menu. Not to mention a delicious array of tacos filled with beef, pork, chicken, and chorizo. Check the website or Facebook for days of operation. Open 11 a.m. to 9 p.m.
