Late night picking up Husb in Financial District ..Hungry No reservations. Look in window of Radius Bar--empty...to the bar... Can order from bar menu or regular menu. I chose bar burger. Its not cheap at $17.00 but very very good ...done Med Rare as requested.Thick juicy and ground for maximum flavor and texture. Served on ( I think ) brioche roll ( which was just okay ) and topped with cheddar,hint of horseradish and tiny fried onion rings. Held its juice and heat ..Delicious served with side of divine fries...Like Caffe Umbra burger alot.. this is better ..bartender also made a mean straight up perfect temp daiquiri..
