Oops - no breakfast at Traxx. Recommendations in the area?
Try CAFE METROPOL (http://www.cafemetropol.com/) in the Arts District, which is just a few blocks south of Union Station.
Also, I believe the AZALEA at the New Otani Hotel provides breakfast.
A bit further south is LIBERTY GRILL (http://www.liberty-grill.com/index.shtml), which is a bit of a hike from Union Station.
