Clayton's 92-year-old Seven Gables Inn was recently bought by Restoration St. Louis. Among many updates they're working on, they've reinvented the hotel's bar/restaurant as a smart-casual place.
They've expanded the menu (filet mignon, pan-seared salmon in whiskey sauce) while retaining old favorites (hi, pot pie) from the now-defunct Molly Darcy's concept.
The food is great, and very affordable. I wrote about it for @stlouismag - full story linked in bio. Have a read!
