Best deli or sandwiches near union station?

Started working near Union. Looking for the best deli. Was very underwhelmed by Heidi's brooklyn deli.

Adding more info: would prefer it to be walking distance to union bc I don't take long lunch breaks.

What bothered me most about Heidi's is that their bagel is more like a roll. I'm an east coaster so I'm always looking for a good bacon egg and cheddar for breakfast.

Also love the Italian style subs like meatball and eggplant or chicken parm. Maybe I'll try the sandys from sliceworks.

Appreciate the info and help!
