Butterfly Café

Overview

Set inside Tranquility Bay Beachfront Resort in Marathon (2600 Overseas Hwy), Butterfly Café is the refined dinner stop along the Overseas Highway when you want something polished but still relaxed. Expect American and seafood dishes with Keys‑meets‑Caribbean touches, a warm dining room with wicker accents, and a covered patio that looks toward the bay.

What to Order

Regulars rave about the scallops with pesto risotto, crab cakes, and a memorable Key lime pie. Portions are generous, and the bar program leans into classic cocktails and a solid wine list. Gluten‑free options are available and handled thoughtfully if you flag them.

Seating & Vibe

You’ve got two moods: an elegant, intimate dining room or the outdoor patio for breezes and bay views. Service is a strong suit—attentive without hovering—making it a favorite for birthdays and special occasions. It’s inside a resort, so expect a bit of foot traffic and families passing through.

Reservations, Hours & Pricing

Dinner runs nightly from 6:00–9:00 PM, and prime tables go fast. Reserve in advance and choose “Outdoor” during booking if you specifically want a patio table; otherwise you’ll be seated indoors. Takeout is available by phone if you’d rather dine back at your lodging. Pricing lands in the upscale range for the Keys.

Best Time to Visit

If you want a quieter meal, target the 6:00 PM seating on weeknights. For the patio, arrive a few minutes early to settle in and enjoy the evening light over the bay.

Holiday Specials (2025)

Look for seasonal one‑offs: a Thanksgiving buffet on November 27 (2:00–8:00 PM), a Christmas buffet on December 25 (2:00–8:00 PM), and a three‑course New Year’s Eve dinner on December 31 (4:00–8:45 PM). Reservations are required for these.

Getting There & Parking

Located within Tranquility Bay, you’ll use the resort’s on‑site parking and follow signage to the restaurant. It’s straightforward off US‑1 and an easy add to a Marathon‑based Keys itinerary.
