"The shops are mostly in Chicago’s suburbs. The kids in those small towns grew up and moved to the big city. Those newish residents caused much hoopla when Portillo’s recently opened city locations in Avondale and South Loop. The drive-thru in River North is an operation to behold. The chain’s Italian beef and hot dogs present Chicago street foods in a comfortable chain restaurant setting. The chocolate cake, made with sour cream, even inspired the luscious version that appeared on FX’s The Bear." - Ashok Selvam
