I saw Dylan’s tweet looking for Durham suggestions and figured the easiest thing to do was start a topic. I live in Raleigh now but my wife (also an M alum) got her masters at Duke in 2007 & Durham is an excellent food town. Happy to give more suggestions depending on price and food preference but here’s a few less expensive options to get you started:
Lilly’s Pizza is legendary in Raleigh & now has a sit down place in Durham. It’s won many awards from best in the state to top 10 in the country & everything is local/organic–their salads are also excellent. lillyspizza.com
Bull City Burger & Brewery has good burgers, great French fries ( I like the dirty fries) and brews a decent beer. bullcityburgerandbrewery.com/Bull_City_Burger_and_Brewery/Home.html
Taqueria Vaquita is a taco stand not far from the Duke campus. Outdoor seating and good authentic food.
Guglhuph is a European bakery cafe that does good breakfast and sandwiches.
Scratch is a bakery that does a good breakfast
Toast is a Italian inspired panini place that has very good sandwiches
The Federal is an English Style pub close to East Campus with excellent food as well. Generally a grad students and townies crowd.
Green Room is a dive bar/gaming hall memorialized in the movie Bull Durham. Usually a laid back mixed crowd with great beer selection and jukebox.
