Jennifer Aniston, Justin Theroux Smiles, No Smiles

Jennifer Aniston and Justin Theroux were all about smiles Saturday night ... both embracing and avoiding them.

The couple everyone's watching got some grub at The Smile restaurant in NYC, but were stoic on the way out.

Everyone's reading her lips and her expressions.  Just like old times.
