An office lunch does not need a theme. A burger, fries and a soda arriving in one coordinated order beat ten separate app notifications.
D’s Diner has dedicated catering links for both Sonoma County locations. The menus are not identical, so the first decision is geographic: Santa Rosa or Sebastopol.
Santa Rosa keeps the offer very simple
The Santa Rosa catering menu currently lists a Lunch Special: cheeseburger, fries and soda, sold as ten meals for $120. That makes the cost and minimum visible before the organizer begins collecting names.
It fits a crew lunch, school staff meeting or casual company meal—American comfort food without a committee meeting about lunch.
Sebastopol gives the group more directions
The Sebastopol catering page lists several choices with a ten-order minimum: a cheeseburger meal, kids burger with salad, D’s Special Breakfast, D’s Classic Burger with fries, BLT with fries and a big dog with salad.
The current listing does not publish usable prices for those choices, so prices should be confirmed in the live menu or directly with the restaurant before the order is presented to the group.
