Just recently, my daughter and I have "discovered" Ferguson. I have lived in St Louis for 35 plus years, and just recently visited Ferguson for the first time. It turns out I've been missing out! This is a nice little restaurant on a small hill right off of South Florissant Road in downtown Ferguson. It is located adjacent to an old railroad track. The inside is configured as if it were a train depot,. You order your food at the "arrivals" window and pick it up at the "departures" window. Your receipt for your food is a "boarding pass" with your order # on it. Various sandwiches and the like are available. We just ordered a sundae and a concrete (these are made with custard and can be turned upside down without spilling). Normally,the concretes in St Louis come with vanilla custard with other ingredients being mixed in. However, The Whistle Stop also has chocolate custard, which is very rich and yummy! Prices are reasonable, service is good. Definitely worth a try!!
