Which Restaurant Dishes Can You Not Stop Ordering?

Certain menu items call you back over and over again, whispering their siren songs in your ear the moment you walk into your favorite restaurants. In this town of local sourcing and ever-rotating menus, there's always something new to try, but certain dishes keep calling you back, and you accidentally never order anything else. This week's Friday Open Thread wants to know: which dishes are you helpless to resist?

Which high-end favorites always mark a special occasion, and which greasy-spoon delights can you just not quit? Which dishes can never ever ever ever leave the menu? Leave your thoughts in the comments, or hit the tipline. The results will be fodder for a map next week. This thread was inspired by one on sister site Eater Portland.
