Miami Slice Key Biscayne - Review - Key Biscayne - Miami - The Infatuation

"You no longer have to stand in the annoying lines at Downtown’s Miami Slice to get your hands on their exceptional pies. The pizza shop has a pop-up inside Flour & Weirdoughs in Key Biscayne. They say they’re takeout-only, but their interpretation of the rule is rather fluid. Yes, the pizzas are served in to-go boxes, but no one will stop you if you grab a seat, and guzzle those slices of the “pepperoni proper” with a can of Tripping Animals beer. And, to be clear, you'll want to guzzle. Every inch of that pizza is covered in thick pepperoni cups. (Top yours with dollops of cold stracciatella for an even better eating experience.) That one and “the salsera," which tastes like vodka pasta on a pizza, are so good that you’ll forget you just paid $8.50 for a slice of pizza. Miami Slice is serving the same menu of pizzas here as their Downtown location, and it’s open Wednesday to Sunday from 4pm to 9pm. photo credit: Mariana Trabanino" - Mariana Trabanino

Came here after a day at the beach because we kept hearing about “the best pizza in Miami.” Line was pretty short and we just wanted to try a few slices, so we ordered a slice of the pepperoni, the truffle mushroom, and the bacon leek. We wanted the marg pizza with “the works” or whatever it’s called, where they drizzle it in hot honey and add basil and stracciatella, which is what they’re known for, but they were out of the stracciatella. Go figure. You’d think a place known for making a pizza a certain way wouldn’t run out 2 hours into business (they open around 4 and we got in around 6). My main issue here is the service. It wasn’t very busy when I came in, I told the cashier that this was my first time here, so he knew I wasn’t familiar with how long they take to get pizza out. I sat at one of the little tables where he could clearly see me, and waited. And waited. And waited… it starts to pick up and I see people come in after me and get a whole pie and leave. I think ok maybe they ordered ahead. Maybe my specialty pizzas take longer than normal. Maybe they have whole pies ready. Then I overhear a family order a pizza, wait, and get multiple pies, while my wife and I are still waiting for our 3 slices… by the time I realized I wasn’t getting my pizza, almost 40 minutes had passed since ordering. Guy is oblivious, like he must think I’m just sitting here for almost an hour for fun? Turns out they completely skipped my order, cashier goes to the guy handling the order tablet and he looked like a deer caught in headlights because he probably skipped or marked my order as complete without handing it out. And all I get is a half-ass “sorry” and “I’ll bring it right out to you” which he didn’t. In my experience working in customer service, I would make sure the customer feels compensated for errors. A little something extra, a gift card, a more sincere apology. Not that I’m expecting anything, but after the egregious error of literally forgetting my order and ignoring me while I sit directly in your line of sight for 40 minutes, you’d think the least they could do is compensate in some way. But all I got was the most half-assed, afterthought of a quiet “sorry” and then it’s on to the next paying customer. Maybe because I was irritated, hangry, tired, or all of the above, but the pizza was… alright. Not crazy. Not life-changing. Not the best pizza in Miami. Maybe I’m spoiled by Mister O1, Local Pie, etc. but it just didn’t amaze me. The crust did have a nice char to it, the slices were big, but the flavors need some work. The truffle mushroom was lacking truffle flavor and tasted more like mushroom gravy on bread than a truffle cream pizza. The bacon leek was probably my favorite because it was more unique, and the pepperoni hot honey was decent. Another negative here is that it’s not designed to make you want to stay and eat here. I understand this is a pop-up at the Flour and Weirdoughs bakery, but it’s very obvious that the tables are thrown in like an afterthought. Pizza tastes best when it’s fresh, right out the oven. Taking it home only reduces the experience. On top of that, these slices are expensive. They charge you like you have nowhere else to go for pizza. I paid about the same for a huge slice of pizza at a music festival recently, and I actually did have nowhere else to go! For the price you pay, you should at least expect quality service and exceptional pizza instead of decent pizza and being ignored by an old man with a man bun. Come here once, hope they have what they’re known for, set a timer after you order in case they forget you, try it to say you did, and then go somewhere better for your next slice of pizza. I don’t see myself returning to this location. Maybe I will go to their original location and try the pizza with the works (if they have it) since that was really the one my wife wanted to try in the first place.

Miami Slice in Key Biscayne is amazing! The service was friendly and fast, and the pizzas were outstanding. I tried the Leek on Bacon and the Pepperoni Proper — both were incredible, with crispy crust and great flavor. The place has a nice vibe and good prices. Definitely one of the best pizza spots in the area!

I have not visited this restaurant yet, but I have seen the residual effects that it leaves on the island. I have seen multiple cardboard boxes thrown on the side of the road all with the signature logo of Miami Slice. It’s great and all that you guys make amazing pizzas and I’m really happy for you, that much is true. But you are contributing to the downfall of keep Biscayne ecology. Is it really necessary to put two slices into a large thick cardboard box that eventually gets thrown on the street? I would normally say that that topic is up for serious debate but the fact of the matter is, no it’s not all right. I will be reporting these facts to the city council And I will ensure from here on out that your company is held responsible for each and every cardboard box that is thrown on the side of the road. You spent so long trying to innovate your pizza, but you certainly didn’t spend any time trying to innovate the absolute waste of paper That is plaguing each and every neighborhood that you worm your way into.
