I've happened upon an optimal time for Schwartz's: raining, 11pm Friday evening. I was in & out in 5 minutes with my soon-to-be translucent paper bag of hot smoked meat.
The bread in this sam'mich is clearly just a juicy beef delivery device, measuring less than a centimeter in height, just dense enough to provide some grip on the succulent slabs of protein as you direct it into your face.
Staff was courteous, attentive, and spoke perfect English. The young man behind the counter took the time in between orders to ask the lovely ladies at the closest table how they were liking their choice.
Quick ordering process run-down: you order at the sandwich counter right inside the door, you get a receipt, spin 210 degrees counter-clockwise, pay the man at the till, then take a new paid receipt back to the sandwich counter and receive your sandwich after it's hand cut and assembled with some mustard.
First experience: great. I'll be back the next time I notice the stars have aligned and there's not 30 people outside waiting for their beef injection.
