The best cheesesteaks in Chicago.

Portillo's is not a discovery. It is a Chicago institution, and this location operates accordingly: a two-floor room built to handle volume, with kiosk ordering at a central ring and the kind of square footage that seats a crowd without apology. The setup is fast-casual at scale, and the room runs like it knows exactly what it is. The Chicago-style hot dog is the anchor here, and it earns the reputation. Vienna Beef on a poppy-seed bun, dragged through the garden with mustard, relish, onion, tomato, pickle, sport peppers, and celery salt.

No shortcuts on the build, no ketchup anywhere near it. The fries come alongside and hold up as the right accompaniment. For anyone new to Chicago who has been told to try an authentic Chicago dog, this is the location most visitors end up at, and the dog itself does not let the city down. The Barnelli's side of the menu broadens the offering, running pasta salads and Italian options alongside the Portillo's hot dog and beef program. The Italian beef is on the menu, and for a city where that sandwich is civic currency, its presence here matters.

The volume this room moves means the beef stays in rotation and does not sit. That is the practical upside of a high-covers operation. The service holds even when the room is running hard. Staff manage the order flow with enough attention to catch and correct errors without friction. For a location of this size, that counts.

The price sits in the moderate range. This is not a special-occasion room. It is a Chicago-staple room, useful for anyone who needs to eat well and quickly in a city where the classics earn their place on the menu every single day.

Manny's Cafeteria & Delicatessen on South Jefferson Street in the South Loop works cafeteria style. Diners grab a tray, slide down the line and point at what looks good behind the glass, a setup that feels chaotic and fun. The dining room is bigger than first-timers expect.

Corned beef and pastrami are hand carved and stacked on rye, and the Reuben is ranked among the top in the city. The matzo ball soup is hearty, the potato pancake is giant, and the half sandwich and soup combination is a popular way to eat. Breakfast items such as corned beef hash and challah French toast are served, along with a bakery counter.

Practical notes: portions are huge, prices run high, and the line moves quickly, with staff pushing diners along. Some diners found the corned beef dry or the soup bland on a bad visit. Parking is available but fills at lunch. Deciding the order while waiting makes the line easier.

Mr. Beef is the Italian beef standard that Chicago keeps returning to, a counter-service sandwich shop that has operated long enough to become civic shorthand for what the city's signature sandwich is supposed to be. The room is spare, the line moves, and the operation closes at four in the afternoon because it does not need to be open longer than that. The sandwich itself is the point: thin-sliced seasoned roast beef on a roll, dipped wet in jus, finished with giardiniera or sweet peppers. That is the Chicago beef in its correct form, and Mr.

Beef does not complicate it. Order it hot and dipped and the roll absorbs enough jus to hold together without dissolving, and the giardiniera brings the heat that makes the whole thing make sense. This is not a French dip. The beef is seasoned and sliced thin and the dip is part of the construction, not an afterthought on the side. The shop drew national attention after The Bear placed it at the center of Chicago Italian beef culture on television, and out-of-towners now make it a stop.

That is fine. But the room was never built for tourism, and it does not perform for it. The counter is the counter, the hours are the hours, and the sandwich is the same sandwich it has always been. Locals who grew up in Chicagoland and somehow never tried an Italian beef have been correcting that oversight here. Moderately priced, counter service, no-reservations.

The early closing time is the one operational fact that shapes every visit. Get there well before four, because the line at the end of the day reflects what the room already knows about itself.

The Original Nottoli & Son on West Belmont Avenue is a small Italian deli and market, with seasonings, sauces, frozen pizza and imported goods on the shelves. Diners say the shop feels like home and beats any chain sandwich shop. Homemade pickles are a surprise favorite.

The pot roast sandwich is the dish named most, tender and juicy. The Italian sub, meatball sandwich, chicken cutlet, chicken parm and Italian beef also earn praise, and macaroni salad, tiramisu and cannoli sit at the counter. Sausages and hot dishes complete the menu, and catering is offered for parties.

Practical notes: the shop gets busy fast, with lines about ten customers deep. The staff work quickly, and calling the order in avoids the wait. Signs mention short staffing at times. A few diners reported a bitter onion, a salty pot roast, or an upset stomach after a sub, so freshness is worth asking about.
