With most diners, you eat at them because you're in the mood for comfort food, or because it's close by and you're hungry, or because you're hungover and need some greasy stomach-filler, or because it's 2 a.m. and your options are limited. Twin Citians might eat at Mickey's Dining Car for all those reasons, but mostly they eat there for the experience. The 70-year-old downtown St. Paul train car is not just a diner but an icon, a rite of passage, a throwback to simpler times. Luckily, it's not just an experience — it's also got pretty good diner food. Mickey's is worth going to for the all-day breakfast alone, it's been making its famed mulligan stew from a recipe almost as old as Mickey's, and its malts are concocted from real ice cream. The One-Eyed Jack is a special treat: a grilled ham sandwich made with jack cheese and fried egg. A classic sandwich in a classic diner.
