I've been told by my coworkers for the longest time how great the Grand Concourse is for Sunday brunch so when my Mother came to visit I figured we would check it out.
We easily made reservations for Sunday morning. When we arrived, the staff told us they were backed up so we walked near the river, which is a great place to check out some left over machines from the Steel Mill days.
The Grand Concourse is an old train station turned fancy restaurant. Make sure you come hungry because there are so many fantastic options. The ambiance is amazing with panoramic views of the city. The building is from the early 1900's so you feel like you are in the 1920's. As for the food, let's just say it is magnificent and you won't leave hungry. The staff is constantly changing the food at the buffet so everything is fresh and tasty. There are so many wonderful options. The made to order omelets are second to none and the carving station includes top quality meats.
If you're looking for great quality food and awesome ambiance in your dining experience in Pittsburgh, I would absolutely recommend coming here!
