I have had only excellent experiences with Zigatos. They used to be located at Howe 'bout Arden, but have recently moved to the site of the Canterbury Inn off Hwy 160.
The additional room gives them tons of space for their catering business, which consistently ranks among the best in town. They are very creative and would go the extra mile to make the picnic fun and unique.
Zigatos catering arm is known as Capital City Catering... you can reach them at 916-641-6111 or capitalcitycatering.com
