3.5 / 5 (71 reviews)

Description

The Filament, nestled within Diamond Jo Casino, offers a mixed dining experience that leaves patrons with varying impressions. While the food garners consistent praise for its flavor and generous portions—particularly the sliders, cheese curds, and calamari—service has been a recurring issue. Long wait times for seating and inattentive staff mar the atmosphere, despite a friendly environment. Guests appreciate the quick food service, yet some report billing inaccuracies and hearty suggestions for improvement. Overall, The Filament presents a promising menu that shines but struggles with execution, leaving diners hopeful for enhanced service in the future.

We absolutely loved the pea coleslaw that accompanied the fish and chips; in fact, we'd consider returning just for that side dish alone! However, the Reuben egg rolls were a disappointment; the meat was over-mixed, which resulted in a lack of texture, and there was barely any sauerkraut. One member of our group described them as having “great flavor, but atrocious texture,” comparing them to “wet dog food.” On a brighter note, the bourbon sliders were fantastic—like having caramel on a burger!

The food here is consistently served quickly, and everything we’ve tried has been delightful. I highly recommend the Iowa Pork T sandwich paired with their Korean BBQ sauce. The French fries are excellent, and the cheese curds are among the best you’ll find anywhere.

I went here to watch the Super Bowl—go Tampa! I loved the food; the Reuben egg rolls are amazing and absolutely delicious. The dessert cookie with ice cream was just as good as our juicy burgers. I only wish they still offered pomegranate margaritas, but no complaints otherwise!

Food is amazing, it's quieter here and it's great fun to watch other gamble. The service is slloooowwee and took forever to get seated.

We visited The Filament for a quick bite while visiting Diamond Jo Casino.The wait to sit was awful. It was only myself and my husband in line. Four members of staff walked by us numerous times in ten minutes without even saying a word or making eye contact. There were several visible tables available, and we even watched two of them stand chatting while changing channels on the TV. Still, ignoring us.Once seated our water and soda came fast, and our order was taken. Since we were just grabbing a quick bite we shared the Bourbon sliders and cheese curds.We were not disappointed with the food at all. The sliders were cooked perfectly, served hot, and every morsel was delicious. The cheese curds were classier than what I am used to, and I'm from Wisconsin. They were flavorful and hot.Overall, very good value, and excellent flavor. Staff was poor.
