Fat Boy's Diner

This restaurant is located just before the bridge to Missouri. Its an easy in and out parking lot. You can see the river and marina from most of the seating. I would love to visit in the winter to see the eagles. We ordered 3 things and they were all fresh and very tasty. 2 of us had so much food we brought it home! The tenderloin was easily enough for 2 people. I would definately visit here again if i was in the area!

Ordered to go, food was amazing! One of the best tenderloins I've ever had; it came out in a pizza box it was so huge! Was tender and thick, too.
Also ordered catfish fritters that were also great.

I had the Philly Cheesesteak sandwich and Cole slaw. The food was excellent as was the service. Very friendly staff. The dining room was spotless as were the restrooms. Highly recommend Fatboys.

Goodness! The biggest pork tenderloin sandwich I've ever seen! Great! Could not even finish it. Very good! You could hear back in kitchen the chefs, cooks pounding more out for the next day!

Great place! Go take a walk down by river once your done eating!

Had a private party. Owner very accommodating! We had appetizers, toasted ravioli, mozzarella sticks, and garlic cheese curds. Very good!

Pork Tenderloin dinner is outstanding. Crisp and made fresh.
Bring your appetite. It's as large as the dinner plate.

Very nice place to eat. Food was delicious and the staff is very friendly. Gwen was our server and she was wonderful. Everyone loved the food and the Fat Boys Tenderloin sandwich has to be experienced. (it was very good!)

Massive... Pork... Fritter.
lol, this thing is so big, and it was delicious!! I loved the breading and it was quality meat. Fun place to check out right next to the marina.

Amazing place for a quick bite or a cold beer/drink. Servers are so friendly and know the menu by heart. Love that substitutions or changes are honored and the on house atm is a lifesaver sometimes. Best cold budwesier and wings around !

Very kid friendly! Plus you can just seat yourself! LOVE LOVE LOVE that option especially with rowdy toddlers !

Not to mention the view is amazing. You can sit right by the windows and watch the boats, river or just the beautiful clouds on summer days!

Fish fritters are the best. How do you make tarter sauce

The food is amazing
Like go back there again

We took my sister here for dinner. I ordered the pork tenderloin with mashed potatoes and shared a salad with my sweetheart. The tenderloin was delicious and huge! I had enough to take home for two lunches. We had rhubarb pie waiting at home, so didn't really check for desserts. The pulled bbq pork sandwich was excellant, and Julie give them two thumbs up. Windows face west and we enjoyed watching the sunset.
Our waitress was good and we were lucky. The other waitress was some addled high school student too busy on her phone to even check us out. Very unprofessional, that one. She seemed neglectful of her tables.

Nice big roomy areas, nice dining experience..

Drove up to fat boys from stcharles mo food was so good the blt is not a joke could barely finish it. Very nice place to stop n eat on a little road trip if you put that way make sure to stop by fatboys.

We stopped here yesterday on our way home because of the reviews we had seen. I wanted to try the tenderloin. I was extremely disappointed in it due to the fact it was basically nothing but breading and over cooked. I couldn’t even eat it. The waitress asked if I wanted a box? I said no because it’s not very good. All she said was oh sorry. So I paid a little a little over $14 for it and my drink and couldn’t even eat it. I will not eat here again! *** update ***
I was contacted by the restaurant and they are going to make things right for me. I am definitely willing to give them another try. Thank you!

I ordered the catfish fritters and Mac n cheese. The fritters were delicious! Another person at our table ordered the cheese bites and they were soooooo good! Our waitress was great as well, especially with us being a fairly big party.

The pulled pork was delicious, as was the house BBQ sauce. Service was fun and friendly. Glad we decided to try across the river.

Outdoor seating looked fun, but it is the 3rd of July and midday. 😉 If we had been there in the evening I would have loved to sit out there around the fire pit and watch the water and boats in the marina.

I love the atmosphere n most definitely the food. I have had the...loaded omelet n stuffed gay boy burger n the chicken Philly n oh my all was amazing.
The people working there are all very friendly. The owners are very loving n make sure they come out n check on their customers too. Customer interaction is always a plus.

Keep up the awesome work n will be back again soon.

Food was good. Waiters f
Very nice and helpful. Somethings on menu a little pricey overall not bad would and do plan to return.

Went out to lunch with a friend who has had many fish dinners through-out his life. His comment regarding the cat-fish platter, "This is some of the best fish I have ever eaten." Great service. Nice location. Friendly staff. A great asset for the Louisiana, MO community. Please give them your business.
