Dinner at a restaurant lasts an hour or two. The memories linger much longer, especially when you were celebrating an engagement or anniversary, a new job or promotion. For these special occasions, you seek out special restaurants, not the newest or trendiest, but the places that have withstood years or decades in a turbulent industry — the places that feel like a second home even when you haven’t dined there in a long time.

We asked for your memories of St. Louis-based restaurants that have been in business for at least 20 years. This is what you shared. Entries have been edited for length and clarity.
