One of my best friends, her husband and two small children are moving to St. Louis for a year. I want to put together a guide of sorts for them of fun things they can do while they're there. I'm looking for hidden gems, "a place only the locals know," "if you go to one restaurant it should be..." -- that kind of stuff. They don't have to be kid-friendly, although some kid-friendly options would be great. They're pretty adventurous eaters, so nothing is off the table (haha). Thanks!
