We were there this past March, with a lounge reservation, and were able to order sides (parmesan potato wedges, roasted carrots and broccolini) and dessert from the restaurant menu to go with our short rib sliders from the lounge menu. It was all delicious! The waiter said we could order from either menu in the lounge. I’m not sure how that would work with the items on the restaurant’s prix fixe menu though.
