    Tried this spot for dinner and overall had a really good experience! The spinach dip was delicious--definitely a must-try. I loved that they offer mocktail flights--such a fun and creative option, especially for those who don't drink. We ordered the buffalo chicken pizza, which was just okay for me, but to be fair, I'm partial to Plank Road Pizza's version (which I think is the best, though theirs is on the smaller side). What absolutely stood out, though, were the Cloud 9 wings--hands down the best wings I've had in the area! Schlafly comes in second, but these were next level. Service was great, really friendly and attentive staff. The only downside was the number of flies--they were pretty relentless and made it hard to fully enjoy the meal at times. That said, the atmosphere was relaxed, and it's definitely a solid dinner option in the area. Would come back, especially for those wings and mocktails!

    I really like Mellow Mushroom. It's one of the few places where the crust is sooo good. The pretzel bites with cheese is a great way to start off the meal. I love a good salad, and they have several to choose from. You can customize them, however you like. I've tried several different types of pizza and I really like the Holy Shiitake. The truffle sauce on top elevates it. The bar frequently offers fun events like trivia. The restaurant is a whole vibe. If you enjoyed the 80s MTV era, this place is for you.

    Really a fun place with great pizza at a reasonable price. We went about 4:00 on Sunday with no issue getting a table for six. We had a big booth in the dining area but there is also a large bar area with tables. The decor is bright and fun! They sell some cute T-shirts and hats too. Our waitress was great and the pizza was ready pretty quickly. The pizza has a nice thick crust and the sauce...yum! We will come again when in town.

    Mellow Mushroom has been my family's favorite pizza place for a few years. We love the Greek salad. We usually order a regular salad and split it. You can't go wrong with the sausage, pepperoni and mushroom pizza. The crust is always amazing especially when dipped in blue cheese dressing. Every time we visit, we always get seated right away. The service is alway friendly and helpful. The place is always buzzing with patrons. Everyone is always pretty chill.

    We took our four grandsons here for a late lunch. They were starving and we had to coax them away from Taco Bell to try something new. Mistake. The only bright spot to this visit was our server "N". She was great. The food was terrible. Three kids Mac and cheese dishes were supposed to come out early. They ended up coming out a full 10 minutes after the other dishes came out. The kids were near passing out when they dove in. Almost simultaneously, they literally spit out the food and declared "it's cold". "no way..." Sure enough I took a bite and it was totally chilled. Like... fresh out of the fridge. Now, I'm not sure what MM does to prepare fresh, steamy hot Mac and cheese, but it doesn't seem to involve fresh steamy hot Mac and cheese. I'm curious how the cooks were trained. I'm now also curious just how "freshly made" the food is. I'd also like to know why it takes longer to serve cold Mac and cheese than it does hot. As for my sammich... The filling for this "sandwich" was about 1/4 " thick. Jimmy Johns #9 is 10x's fatter, tastier, and they're cheaper. I would recommend you steer clear of Magic Mushroom until they can get some people who know how to cook in their kitchens. I wish "N" all the best. She deserves an establishment that can support her hard work with quality food.

    It's been years since I visited MM. Tired of the same old places, we ended up here. The two of us decided to share a couple of dishes. We selected the Stuffed Portobello and a Holy Shiitake pizza. The first dish was surprisingly tasty, warm on fresh greens and drizzled with vinaigrette. The pizza also hit the spot, and it's clear why it's so popular. The service was excellent. Our server was friendly and attentive. It was a much better experience than when we were here a few years ago. I'm certain we are going to return to try a couple more dishes. We probably won't wait four years this time!

    Location near the college, mall and the hustle/bustle of Mid Rivers makes this an easy destination. Fun atmosphere, great service and good food make it a go to2ce back for food and fun.

    Was decent food. Service was good. The place looked like it could be a little cleaner but was not a turn off.

    They have unusual pizza offerings or you can design your own. A little pricey but worth it. They have good salads as well.

    How do I make a reservation?

    I don't think they take reservations, but during busy times you can use Waitlist on their business page, right in the Yelp app, to get in line before you arrive.

    Is the patio dog-friendly?

    Yes! Just don't let them get your pizza!🐶

    Noto is another reminder that great Italian restaurants can absolutely keep my pescatarian soul…read morehappy. I ordered the shrimp pasta, and it easily earns my #stlouispescatarianapproved stamp. The shrimp was cooked perfectly, and the pasta had a great spicy flavor. I detest a heavy pasta. This one was one was perfect! We sat at the bar instead of a table, and I actually preferred the more relaxed atmosphere. We also shared a pizza that had a perfectly crisp crust. Lil brother got the pork chop (I'll take their word for it, I don't eat meat), and we finished the meal with affogato, which was a great way to end dinner. So glad I finally made it here.

    We do a double date with some friends every month and this spot is near their house. They highly…read morerecommended it. We're not usually Italian foodies but....oh my god. This place was amazing. I've been recommending it since. We spared none and got literally too much food because we couldn't decide what we wanted. And no shame. I'm so glad we did. We shared appetizers, a salad, pizza, and a pasta. And woah. Everything we tasted was fantastic. I don't think there's anything bad on the menu. If you're looking for a dinner spot, look no further. Great cocktails as well. Highly, highly recommend.
