UPDATE: Findlay's moved to Knoxville in late 2009, they are just a block off the main square. I saw it was just a BBQ place with the same menu but no meat market. This current location is now named Two Rivers BBQ Market and Deli, they have a tenderloin but I haven't made it in try one yet.
This butcher shop has a wide variety of meats for sale, and a lunch menu that includes a homemade tenderloin. The big meat smoker outside told me that tasty meat would be served here. Unfortunately, subsequent visits have revealed the tenderloin is no longer on the menu. Bummer.
Location: 1951 Indianola Ave on the south side of Des Moines.
Directions: Take south 7th St. from downtown, turn on Indianola and find this building beside Italian-American cultural center.
Price: 4.99 , with chips and a side for $1.50 more.
Also on the menu: Smoked meat BBQ sandwiches, a full meat selection for large orders including Turducken. Jerky was in stock when I stopped by.
Service: Counter service, it can take a few minutes to get your food.
Ambiance: Bright light from windows comes into dining area. There are signs with meat prices outside. The place gets crowded for the lunch rush.
Final Thoughts: Smoking the pork loin before breading and frying can bring out a world of flavor. This relatively new butcher shop has a solid tenderloin worth checking out, its too bad it was discontinued or moved to "seasonal" status.
For emergency Tenderloin craving: head further down Indianola and turn on Hartford to reach B&B Grocery for their Big Piggy Pork Loin or Real Tenderloins.
