We're driving up to meet some friends in Cotati tomorrow (Monday, MLK day) but every time we've visited them we've wound up at pretty dull restaurants, so I was thinking we should meet them in Santa Rosa or Petaluma or really anyplace in the area with decent food. There will be 3 kids and 4 or 5 adults. We're looking for something kid-friendly, not horribly expensive, that will be open for lunch on a Monday holiday. Suggestions? Any kind of food is ok.
