If you care most about seeing cool breweries with good beer I'd be sure to hit The Veil, O'Connor, Wasserhund, Back Bay's Farmhouse, and Big Ugly. I probably wouldn't do them all in a day because they're so spread out but they're my favorites. I'd recommend hitting all of norfolk and an area of Va Beach for a long day of brewery hopping, then pottentially snagging the outliers another day. most rotate through food trucks, but you'll have to call or check their calendar to be sure; a few have food on-site.
If you're focused on Norfolk I'd hit Benchtop, Smartmouth, Elation, ( food at hanks? ), The Veil ( food at the veil? ), O'Connor ( normally food trucks? ), Rip Rap, Maker's w/ a cigar.
All pretty close to each other we've got...
