A year and a half ago a little sandwich shop opened in West Raleigh. It had a small following for several months, but for those who have watched the store grow, the secret is obviously out. Dallas-based Which Wich’s store on Lake Boone Tr. is bursting at the seems, so this summer expect Ted, Brandon, and the crew to expand to North Hills and Brier Creek. The North Hills store will be located to the left of the Q-Shack, and will finally deliver a much-needed blow to McAllister’s.
