Taxi to the west end of the airport and go to Beebe's Grill. Hamburgers, burritos, etc. It's located on the golf course. However, I've eaten at the LVK one a couple of times, and found it acceptable. Be prepared for a wait.
Many meals come with salad.
It's unlikely the bowl will be empty by the end of the meal, unless all the diners are metabolic infernoes. We flew in the other day and tried Beebe's Sports Bar and Grill on the NW side of the airfield at the golf course. Good food and quick service. Worth another trip in the future.
