everything to know before brunch.
brunch & menu
Do you serve breakfast?
We serve à la carte brunch rather than a classic breakfast. Many guests come in the morning or at lunchtime for savory and sweet dishes, daily until 2:30 p.m.
Do you have vegan and vegetarian dishes?
Yes. The Veggie Quartet Burrito and the Açaí Mango Bowl are vegan, and the Burrata Toast is vegetarian. We also have oat and potato milk for your coffee, plus alcohol-free cocktails.
Where's the best brunch in Mainz?
We're biased, of course: in Mainz Old Town, at Große Langgasse 12, we serve modern brunch, specialty coffee and cocktails, made with precision and a global twist.
reservations & groups
Do I need a reservation?
We recommend booking online, especially on weekends. Walk-ins are welcome depending on availability. Reservations are for brunch tables only – bar seats and coffee-only visits can't be booked.
How do I book for a group?
Parties of 1 to 6 book online. For 7 to 15 guests, send a group request: credit card guarantee, one shared bill and one main dish per person, 2 hours at the table. For 16 or more, we'll plan your event with you at the butter.fly event boutique.
How long can I stay?
1 to 3 guests: 1.5 hours. 4 guests: 1 hour 45 minutes. 5 guests or more: 2 hours. We hold reserved tables for 15 minutes past the booked time.
Can I rent the venue privately?
Yes – for private events, there's our butter.fly event boutique: 1,076 sq ft (100 m²) with our own kitchen and bar for up to 120 guests, no curfew.
gift cards
Can I buy a gift card?
Yes. On our gift card page, you can order a gift card for €30, €50, €75, €100, €150 or an amount of your choice. We email you the invoice and, once payment arrives, the digital gift card with a QR code – plus a printed card by mail if you like. Service fee €3.50 (waived for €50 and up), or €5 with a printed card including shipping. Valid for 3 years from the end of the year of purchase.
How do I redeem a gift card?
Show the QR code from your gift card email (on your phone or printed) or the printed card when you pay. If the bill comes to less, the remaining balance stays on the card for your next visit.
hours & visiting
When are you open?
Monday to Sunday, 10 a.m. to 3 p.m. The kitchen and bar are open until 2:30 p.m.
Is butter.fly accessible and family-friendly?
Yes. We have step-free access, an accessible restroom, a changing table and high chairs, and the space is air-conditioned.
Can I work on my laptop?
We're not a coworking space. Laptops and tablets aren't allowed on weekends and public holidays. Monday to Friday, you can use them for up to 60 minutes at seats our team approves.
