This place is my new go-to for Italian beef now that they no longer serve it at Famous Uncle Al's. It's good, but not great, and purists will bemoan the underwhelming seasoning of the beef. But you can't beat the price, especially as part of the lunch combo, which adds fries and a soda for next to nothing. Even if giardiniera are extra this is still a great value.
The ciabatta on which the sandwich is served is good enough, but the bread's not as important when it's soggy from gravy. Fortunately, the au jus that Rosati's includes is more than good enough to make up for the underseasoned beef.
Combined with the giardiniera, this sandwich is filling enough that you don't even need the fries that come with the lunch special.
