About Miami Slice Key Biscayne
Miami Slice's Key Biscayne pop-up runs inside Flour & Weirdoughs on Harbor Drive. It is the destination-slice choice in this guide: order at the counter for a slice or a full pie, then take it to go. The schedule is narrower than an all-day pizzeria, so check the official site before walking over.
How the Key Biscayne pop-up works
This is not a conventional dining room with reservations. Miami Slice operates its island pop-up inside Flour & Weirdoughs at 19 Harbor Drive. The restaurant says guests choose dine-in or takeout when they arrive, orders are taken one at a time, seating at the slice bar is limited, and reservations are not offered. Treat it as a walk-in counter stop, especially if you are feeding a group.
The useful distinction from the other pizza choices is format: this is where to go when the slice itself is the plan. The Key Biscayne location serves the Miami Slice menu in a smaller bakery setting rather than trying to cover pasta, salads, or a broad family menu. Pepperoni Proper and La Salsera are the two clearest starting points if you have not been before.

Hours and ordering
The official schedule is 4–9 PM Monday, Wednesday, Thursday, and Sunday; 4–10 PM Friday and Saturday; and closed Tuesday. Those are dinner hours, not an all-day bakery schedule. The direct Toast link is useful for checking whether online ordering is actually accepting orders, but its displayed service window can differ from the restaurant's published opening hours. Use the official Miami Slice schedule for planning and the live Toast state for ordering.
For pickup, confirm the Key Biscayne location before paying: Miami Slice also operates outside the island. If the order screen is unavailable, the restaurant publishes one phone number, (305) 217-5423, across its locations. Walk-in service is the safer fallback during the pop-up's stated hours.
