I used to deliver back in the day here before lockport got over crowded with pizza joints and I would get american legion halls and lodges then like 10 deliveries at once. I was on top of that. I think my best payout ever was damn close to $200 in a night. alot of $120 nights.
Im going to have to say that there is a place near me that IMO is right on par with portillo's as far as taste goes but its not the same style beef as Portillos. They slice (thicker) and cook their beef in house and have a house made gravy they put on the beef. So good! As far as chains go, Portillos all the way.
