Celebrated my 40th birthday here with my family!  A special dinner during a special weekend.  Not only do I think Lawry's has the best Prime Rib I've ever had but I think the way the restaurant is ran, it's one of the best overall restaurant experiences.  The Prime Rib sits in a cart that is brought to your table and sliced individually.  The waitress was extremely polite and impressive.  I can't afford to eat here often but I do believe treating yourself every once in a while is required.  Make reservations early.  We didn't get to go the night we initially wanted due to the popularity.
