Favorite Defunct Restaurants or Dishes

Was talking to a friend the other day about some of our favorite food memories in and around LA that we can no longer obtain. For me, I will never forget the loss of Asia de Cuba at the Mondrian. The lobster boniato mash and the calamari salad were the stuff of legend. The club sandwich and chicken tenders that used to be at Houston's in Santa Monica were unrivaled. My friend said he still has dreams about the brown sugar donuts from Church Key on Sunset.

So was curious what everyone else's most sorely missed restaurants or dishes are?
