I would add a few:
Raleigh TimesSmall menu, but everything on there is excellent. Walking distance from Lincoln Theater, The Pour House, Progress Center (and soon to be the convention center) if that's where your gig is. Kitchen stays open until 2am. Excellent as a watering hole too.
14 E. Hargett St., 919-833-0999
RockfordAlmost all sandwich and salad menu, but it's classier food than that would suggest. Located in the middle of one of the main drags.
320 1/2 Glenwood Ave., (919) 821-9020
Oak City Cafehttp://oakwoodcaferaleigh.com/Authentic Cuban and Argentinian. Only open for dinner on Friday and Saturday. Lunch M-Sa. It's small, so I wouldn't go with a big group but it's good eats. Not too far from downtown gigs, more like a 15 min walk. Two blocks north of Moore's Square if you're gig is there.
300 E Edenton St, (919) 828-5994
Irregarless Cafehttp://www.irregardless.com/cafe.htmlIf you're trying to spend more than your PD.
901 W. Morgan St., (919) 833-8898
Neomonde http://www.neomonde.com/cafe/index.aspxAuthentic Lebanese/Mediterranean+ grocery. You can order by weight if you're looking for some good road food and have a place to keep it.
3817 Beryl Road (turn at the road by Waffle house (not on the list) take an immdiate left, 300 yds. down the road on the left), iffy on their English, but (919) 828-1628
