In our experience, most people who eat at Costello's Sandwich and Sides get the same thing every time. It's their Costello's Match. Former Chicagoist editors Scott Smith and Erin Shea love the Heartland and Smokin' Turk, respectively. Our boyfriend's favorite is the Italian Grinder. For us, our Costello's Match is the Turkey Focaccia.

Generally speaking, the Turkey Focaccia is a basic turkey sandwich — turkey, provolone, lettuce, tomato, vinaigrette. But what makes this sandwich spectacular is that it's baked on the most scrumptious tomato focaccia bread that we've ever had. It's topped with a really delicious roasted garlic mayo. A recent email conversation with Lisa Costello Crampton revealed that Costello's gets their subs and focaccia delivered fresh from D'Amato's Bakery. Lisa told us about D'Amato's retail store at 1124 W. Grand Ave., and you better bet we'll be checking it out soon. Then again ... we're lazy and Costello's is just a few blocks away, so we'll probably just head there for our next fix.

All Costello's sandwiches include chips, pretzels, an apple or a nectarine and run from $5.95 - 6.50. If you're really hungry, upgrade to the Deluxe Meal for $2 more and you'll get a small side (the red skin mash and chipotle mac & cheese are our favorite sides) and a drink. Either way, you've got a completely satisfying lunch for under ten bucks.

While planning to write this post about Costello's Turkey Focaccia sandwich, a few of our friends expressed surprise that Costello's sold foccacia sandwiches. This begs the question: Is it just our group of friends who stays true to their Costello's Match or do you guys have a sandwich you repeatedly order there too?

Costello's Sandwich & Sides is located at 2015 W. Roscoe St. and 4647 N. Lincoln Ave.
