Portillo's is establishing a presence on one of the city's most iconic streets with a new location at 304 N. Michigan Avenue! However, the new location won't be one of its typical dine-in establishments. According to the official announcement from Portillo's, the restaurant "will be one of the first in-line, walk-up Portillo's locations, designed for guests on the go who want a quick and easy way to get their Portillo's fix." #portillos #chicago #michiganave #chicagodog #italianbeef #chicagofood
