Mousalli's Prime is a unique atmosphere, as its location is a house nestled by a wooded area, feeling private and well kept. There is inside and outside dining (has heating and is enclosed in the winter, like when we went). Parking is easily close to the building in any direction as it surrounds all areas of the restaurant. As you walk in the front doors, you are greeted by friendly staff, however, you do walk past kitchen/prep areas to get to the seating where we sat, close to bar area, but nicely nestled where it felt private. It over looked the outdoor seating so we could still see outside, or as in my husband's side, he could see the bar TV's. Our waitress quickly greeted us with a friendly face, advising us of drink options and stating she would have waters and bread right back with her. She did just this, asking if we were ready, or needed more time. In the meantime, she advised us of specials, appetizer options and her favorite picks. We appreciated her expertise and giving us the space and time we needed to decide. Their menu features Coke products to drink and a large selection of wine, cocktails and beer. Choices for everyone. Bread that is brought to the table is a soft style, focaccia (which neither of us are big on) with fancy styled butter. My husband and I both chose steak options. I ordered an 8oz filet mignon, with baked potato and French onion soup. He ordered a 16oz ribeye, baked potato and tai curry chicken soup (a suggestion from the waitress with a spicy kick). I also ordered their garlic parmesan fries because I couldn't choose between the options. When the soups were brought out, again we were asked if everything was well and if we needed anything. The attention to detail on service was on point through our whole experience. Now back to the food...the French onion soup was OUTSTANDING, some of the best we've both ever had! It comes with two cheesy crostini's on top which just added to the delectableness. It has a creamy, delicious, not over powering onion flavor like some can have. Definitely worth trying, even if you aren't a French onion soup gal like myself. My husband has the pallet for the spice, I do not, thus he had the tai curry chicken soup. So his credit for that one is, good flavor, enjoyable traditional tai flavors. Spice scale was a 3/5. Our meal came out hot and huge. Their baked potatoes are ginormous! My husband and I's steaks were both cooked to our liking. He ordered a medium well and I, a well done steak. I know that seams terrifying to some, but I always state, if it's a steakhouse that knows how to cook, then it'll be wonderful! I can attest that the cooks know just how to make a well done steak to perfection. It was still tender and juicy with a beautiful char. All our food was brought out hot and beautifully plated. Soon after we started the owner came out to check on us and our food. My husband and I both agree, this is where you really see the beauty in this establishment. It says a lot when an owner comes out to check on you and your experience. Sadly, he approached me moments after I tried the first bite, so I wasn't quite sure how I felt yet. He could see something was off and asked again if everything was okay. My husband said it was good. My only negative was my seasoning for the steak, it just didn't have as much flavor as expected. Now, saying even more for the care and compassion this restaurant has is that the owner came over again, checking to make sure my food was good. This time I was open and made my statement. He was very thoughtful to apologize and was sincere in taking that criticism. Not that I'm any kind of high and mighty. It was just my personal preference. BUT, he came back, he checked again, and he truly wanted us to enjoy our food and evening and this means a lot to us. Literally the entire time we felt care for and welcome. The service is top notch! More on the steaks, the texture and quality of the beef is excellent! In all sincerity, it was good, just less flavorful in seasoning than I prefer. It was the same for the garlic parmesan fries, just not much to them. The baked potato was great though. As I talked with the owner, I asked about the glaze over my steak, he said this is a 24hr process of creating a veal bone, French style Demi glaze. This was heavy for my taste but I could see others enjoying this touch. Overall, we'd give the steak and sides a 6.5/10 in comparison to other steak houses we've tried local and STL region. It is worth a visit for the overall experience, with very attentive service and care for preparing your food and creating a custom ambiance. read more
