We stopped here for dinner around 11:20pm and enjoyed it. Ashlee was our server and she did a good job and provided us with the best service. The kitchen was about to close when we arrived but they didn’t cut any corners on the food. I had the turkey burger and fries which I enjoyed. My wife had the wings which were also good. There is plenty of seating indoors and outdoors. This is a nice spot with good food and good service in a nice area.

This is a nice, laid-back establishment. The drinks are great, and while the menu can be overwhelming, it offers a wide variety of good options. Our server was attentive and helpful with questions about the menu. I would definitely come back to enjoy a drink or to explore the menu further.

I was in town for a concert and had a few hours to kill. I wanted something close the hotel so I could walk, but wasn’t sure what I was in the mood for. CJ Muggs was right around the corner from my hotel. The place has a bit of a neighborhood bar vibe, while still being in the city. It’s about 15-20 minutes from the airport in the Clayton area of downtown St. Louis. Lots of reviews of the food pointed in the direction of the blackened chicken nachos. So that’s what I ordered. Generous portion and delicious chicken and all the expected toppings one would find nachos. If there is one negative the chicken could have used more flavor, but it was still very good. My server, Maddie, seemed to be running the bar area herself. It wasn’t super busy, but she seemed to be completely in charge of the bar area. She was very attentive with a great attitude. I would definitely go there again when I am visiting St. Louis. The major strike against this place is the insistence on serving Pepsi products. For that I cannot give a full five stars.

Got new ownership the past few years and they've seemed to put money into place. They've updated the menu as well. Overall it still has a great vibe and decent prices. The food is good and the staff has always been great no matter who we get. The staff turnover seems much lower than many restaurants. It has become one of our regular go to restaurants over the years.

Great food, great service, and staff. Good decent prices. Great atmosphere if you are very social person otherwise it's very, very loud and noisy.

This wa my first visit. I was impressed by the variety of the menu and I was excited to try many items. Sadly, my main item needed to reheated by chef "Mike". The sauce was tasty, but fallen apart. The meatloaf binder had fallen apart as well and gave a pallet feel of raw hamburger. Now, the Jambalaya was tasty. Hamburger was over cooked, but tasty. The sweet potato Fries were tasty as well. All-in-all, the meal was okay for a pub grub, but had room for improvement. With a wide variety of items on a menu, many items are cooked on one day of the week , portioned and frozen for use later on. This is a common practice. Having said that, the restaurant must ensure that in the reheating process that the food does not break down. I think this is what happened to my entree. As always, if you enjoyed my review, please hit the like button. Thank you and have a great day
