I have been waiting since the 90's for a pizza-by-the-slice place to be in the Brentwood area. I know there used to be a Mrs Vanelli's Pizza in the mall food court, but that place has never made the cut in terms of good pizza by the slice.. It was overpriced and just wasn't very good.
Fast forward and we finally have Uncle Fatih's Pizza at the recently-opened Solo District. It's good good pizza by the slice and they also have whole pizzas to order with delivery. It's located on the lower level of Solo District on Skyline Drive.
