SOUTH LOOP — Get ready, the new Portillo's coming to the South Loop is just a month away from opening.

The restaurant will open May 31 at 520 W. Taylor St., Portillo's spokesman Nick Scarpino said. Once open, the eatery known for chocolate cake shakes and Chicago-style fare will be the second in the city following a longtime River North spot.

The new South Loop Portillo's will feature two book-ending patios, a green 1928 Ford pickup truck as part of its decor, and serve alcohol like the existing River North restaurant at 100 W. Ontario St.

Founded by Dick Portillo, the restaurant chain is based in suburban Villa Park.

David Matthews and Matt Bubala disagree over cake shakes.
