Wanted to mention a place that opened in the last few months here in Elmhurst called Zenwich. My family and I have been there 5 or 6 times and they make excellent Asian-influenced sandwiches. They have some nice salty/sweet homemade potato chips they serve on the side, along with coleslaw. Our favorites sandwiches are the Mu Ping and the Pork Katsu. Neighbors of mine have tried their more traditional sandwiches and salads and have said they're very good, too.
Zenwich has dinner options they serve with rice, but those have not impressed us (though, to be fair, I think we tried them the first week they were on offer). Given the strength of their sandwiches, I'd probably try the dinner entrees one more time.
They are located at 416 B N York St. in Elmhurst, ~1/4mi north of North Ave and just south of I-290.
