Diamond in the rough! I will be honest and say that when I walked in I almost turned around and I am so glad I didn’t. The food here is AMAZING! The sandwich was grilled to perfection, the bread was a buttery slice of heaven. I had the chicken sandwich (buffalo and dill) If you stop in here and have thoughts about leaving lease don’t. You may never experience this quality of food elsewhere.

My boyfriend and I got a couple sandwiches a couple days ago to try this place for the first time and WOW! So good. We came back today to try 2 different sandwiches and equally as good Hands down our favourite sandwich shop we’ve tried and the price point is amazing for the portions and quality.

This is a true hidden gem. Hands down best poutine in Belleville. I'd even argue in Ontario. Sandwiches are beautiful and the vibe is awesome. Friendly dudes with big smiles and super kind eyes. Definitely worth the adventure to find the place. Will be back to try everything with more poutine.

We stumbled upon this spot while driving through Belleville and it is absolutely fantastic. Delicious and was an incredible start to the weekend and we were just so genuinely impressed with the taste and quality of the food, will definitely be coming back to support this small business. We want to see it continue to grow. Please visit this place!

Expect a bit of a wait especially around lunch time when it gets busy, but my god this was probably the best sandwich I've ever had. I'm just sad that I don't live close by to try all of them. I ordered the Poppa Jones' All Day Beef sandwich and it was delicious. The beef was slow cooked perfectly and the sauce and cheese was amazing. The fries here are really good too, though a little bit salty. The other two members of my group ordered the Nick San meat toro (eggplant Parm) and the chicken pesto and they were both raving about it too. Sandwich and fries came out to about 20 which is actually pretty reasonable considering how good the food is. Will stop by again whenever I find myself in Belleville!

If you havent been to Flossies yet- just do it. This was my second time here and man they nailed it. My mom and I split 2 different sandwiches, mine was the special of the day "the andy bobandy" (lol adorable) and she got the beef one. We mentioned we were going to split and they plated it so nicely for us with one half in each plate and split out fries. Everything was super delicious, and the guy working today was friendly and funny. My mom had never been here before but said she will definitely be back again. She loved the gravy, definitely 100% homemade. Love the chill vibe and the record player too.

Found this place by coincidence last night and came in this afternoon to try. The Sandwich i got was phenomenal (The Andy Bobandy). The two gentlemen working were nothing but class acts and enthusiastically answered all questions I had. Called back after eating and spoke to them on the phone for a few minutes to let them know how good it was and they were nothing but kind and appreciative back. Can’t wait to go back there again ASAP and work through the rest of their compelling menu.

We had heard about Flossies and found ourselves seconds away. The food is all made from locally sourced ingredients and is delicious. The turkey sandwich felt like it melted in my mouth. I would’ve preferred it was not on bread fried but it was still delicious. The eggplant Parmesan was outstanding, crisp eggplant on a soft bun. Next time I’ll try the roast beast.
