While a big fan of Serino's in general, I'm actually not crazy about the store made sausages. I find the capicolas and sopresettas to be too hard, dry, and way too salty. That said, when Elvio, the owner who is almost always there if he is not in Italy, offers a slice of his own made stuff, I never turn it down. There is always some homemade meat in the deli cooler next to the commercial brands. And I trust him, the best thing I ever sampled there (Addison) was a ham he cured himself-unbelievably good.
I never understood the past antipathy towards Serino's, nor saw any shilling, but a moderator said that it indeed happened and they were sure it was employees. When it happened, no one at the store said they even knew about it, and Elvio was totally unaware the situation even existed.
At our shop whenever we are looking to treat ourselves or out of town guests, Serino's is always the first choice, with virtually everyone ordering Italian subs of differing lengths. Extra meat is a great indulgence. The hidden gem though is the daily special that Mama, Elvio's wife, makes each day. Regular sandwiches are also good as we have one ex-Wisconsonite who orders turkey breast with American cheese. Bread is delivered daily from downtown. Paninis and salads are also good, especially anything with eggplant in it. Lots of customers like the pizzas and Italian beefs, but I've actually not tried them.
The deli has some interesting meats;I like the salami with fennel and the mortodella with pistachios. Elvio has also just added a new "machina," a large coffee/expresso machine. The expresso which took less than 20 seconds to make that I had day before yesterday was excellent-small, intense, great crema.
Although the parking lot in Addison was expanded to four times its previous size, it is still packed anytime around lunch, hence the need for the Lake Street, Roselle store. Elvio's son, Bruno, runs the Roselle store. Cooking that Mama does will stay at the Addison store. Serino's even has their own giardiniara specially made by Orlando Greco's.
To my mind Serino's also has a warm welcoming ambiance as well as very good food.
