Portillo's version of the Chicago classic — thinly sliced, seasoned roast beef served dipped or dry on a soft French roll. The beef is cooked in-house and sliced to order, with customers able to choose hot peppers (giardiniera), sweet peppers (sautéed), or neither. Reviews describe Portillo's version as reliable and consistent — a 'safe bet for a good sandwich' though not as specialized as Al's or Mr. Beef. The appeal of Portillo's is speed, cleanliness, and confidence that the sandwich will be made the same way each time.
Tips from diners
The lunch counter moves fast — even at peak times, you'll get your food within 10 minutes.
Ask for it dipped, medium spice — the staff know the sweet spot between flavor and manageable messiness.
Portillo's fries are thicker than typical fast-food versions and have more texture. They're fried until golden and crispy on the exterior while staying tender inside. The fries are salted generously and hold up well in a box during transport, making them ideal for takeout orders. They're a standard sidekick to any sandwich order.
Tips from diners
The fries stay good for 20+ minutes in a box — order them with confidence even if you're eating elsewhere.
Portillo's version of the iconic Chicago hot dog — never served with ketchup (a cardinal sin in Chicago). A Vienna Beef hot dog is placed in a steamed poppy seed bun, then 'dragged through the garden' with yellow mustard, bright relish, diced white onions, fresh tomato slices, green sport peppers, a dill pickle spear, and a sprinkle of celery salt. This is the template all Chicago hot dogs follow. Portillo's execution is consistent and clean, making it a reliable choice for tourists learning the tradition or locals in a hurry.
Tips from diners
Never ask for ketchup — it's considered sacrilege in Chicago. If you want a familiar flavor, stick with mustard.
Grab a combo (hot dog + fries) — it's value-priced and a complete meal.
Portillo's jumbo version uses a larger hot dog for diners who want more meat. It still gets the full Chicago treatment — mustard, relish, onions, tomatoes, peppers, pickle, and celery salt on a poppy seed bun. The larger dog provides more substantial chewing resistance and a beefier flavor profile compared to the standard size.
Tips from diners
Order a mix of standard and jumbo — lets the group try both sizes without over-committing.
The Italian beef refined with hot peppers — the giardiniera adds acidity and a moderate level of heat that cuts through the richness of the beef and sauce. Portillo's peppers are well-seasoned and consistent. This version offers more flavor complexity than the plain sandwich while remaining approachable for most heat tolerances.
Tips from diners
Ask for dipped with hot peppers — the moisture from the sauce and the heat from the peppers balance perfectly.
Portillo's opened as a single hot dog stand in 1963 and grew into a regional chain that made Chicago's iconic Italian beef and hot dog sandwiches accessible across Illinois and beyond. Richard Portillo's business model was to take the traditional Italian beef that Al's and Mr. Beef pioneered and scale it up without sacrificing quality. The River North location at 100 W Ontario Street features a 1930s and 1940s Prohibition-era themed design and serves as one of the chain's busiest locations. While not the inventor of these sandwiches, Portillo's is often credited with making them a nationwide phenomenon. The menu spans Italian beef, Chicago-style hot dogs, burgers, fresh salads, and their famous chocolate cake.
The River North location is massive and well-staffed — even at lunch rush (noon-1pm), lines move surprisingly fast.
Full dine-in seating with a 1930s-themed interior — clean, comfortable, and designed for groups and families.
Open until 1am most nights — a reliable late-night Chicago food option when other restaurants close.
Prices are lower than sit-down restaurants and comparable to other fast-casual chains, with generous portions.
