One other thing in regards to the raffle items being donated. Evergreen Fairgrounds is a real stickler for not allowing any foods to be brought on site to be sold. I think I read in the catalog that NO food items can be donated for the raffle either. You can bring in your own lunch/snacks in a cooler though.
As far as lunch goes, the Thai place is really really good, but also really really small. So I don't think a large group could fit there.
Petosa's is closed.
For a group lunch location, I suggest Alfie's Pizza, they have a great HUGE salad bar, hot subs and pizza and they have PLENTY of open seating.
There's also a Mongolian Grill, Red Robin, Canyon's, Buzz Inn Steakhouse, Ixtapa and Mi Tierra for mexican food and lots of fast food joints.
