At the Traxx restaurant, diagonally across the grand concourse from the bar, diners sit at white-clothed tables in front, lingering over lamb chops or red snapper as they wait for their train to be called over the loudspeakers. Inside is a quiet, dignified dining room in Art Deco style, with a small open kitchen at the back. The restaurant was founded by executive chef Tara Thomas, a California Culinary Academy grad who has a long relationship with the downtown scene. And though Traxx is a more formal restaurant, she’s still serving her signature crab cakes and burgers, along with more polished fare, sometimes with a French or Latin accent. Her menu here offers both small and large plates. Commuters or travelers can grab a quick, civilized bite or meet friends for a longer meal after work.
