Find your next vegan meal in Bonn
Weekend brunch in Poppelsdorf, Japanese–Vietnamese sharing plates, a vegan café break or a buffet assembled your way — four addresses for different appetites.
This guide to vegan restaurants in Bonn brings together plant-based restaurants and a vegetarian-vegan buffet. CassiusGarten is not entirely vegan; the profile explains how to choose the vegan dishes.
For vegan food in Bonn, decide whether you want to linger over brunch, share several small dishes or put together a quick individual plate. This selection gives each occasion its own place rather than treating every restaurant as interchangeable. Use the menu links for your actual date, and keep opening hours separate from the times when a specific breakfast or lunch menu is served.

ESSKALATION
Poppelsdorf · Clemens-August-Straße
Sweet and savoury brunch, with separate weekday services
ESSKALATION's brunch menu offers more than one style of breakfast: scrambled tofu, a plant-based Full English, French toast and pancakes sit alongside breakfast platters. During the week, the restaurant switches to a changing lunch selection; dinner on selected evenings brings flammkuchen, banh mi and bowls. Choose the meal period first, then build an order around the current menu.
Before you book: Reserve for weekend brunch or dinner. Brunch is à la carte, not unlimited buffet dining, and its kitchen window is shorter than the restaurant's overall weekend opening.

Mandala — Bonn
Quantiusstraße · Bonn
Build a meal from small plates or settle on a bowl
Mandala combines Japanese-inspired sushi with Vietnamese flavours and tapas-sized dishes. The current menu includes wontons filled with mung beans, tofu and mushrooms, vegetable gyoza, and crisp tofu sticks with raspberry sauce.

Black Veg
Nordstadt · Adolfstraße
A café break that can become a light meal
Black Veg is a vegan café and bistro with cakes and changing savoury food. HappyCow describes sandwiches, salads and daily specials, while visitor reports from 2026 also discuss cake and hearty meals. Treat those reports as an idea of the style, not a promise that an older burger or special will be available today. The operator's current site supplies the address and weekly timetable.
Before you order: Check the day's selection directly. A complete current operator menu was not available to read during this check, so the menu-enquiry button contacts the café rather than opening an outdated menu.
Highlights: A vegan café-bistro alternative to a full restaurant dinner.

CassiusGarten
City centre · Maximilianstraße
Choose your own mix of hot and cold dishes
CassiusGarten lets you assemble a meal from salads, starters, soups, warm dishes and desserts. The kitchen is vegetarian-vegan rather than exclusively plant-based, and the operator labels dishes to help vegan diners choose. This format works well when you want different components on one plate or when everyone at the table prefers a different combination.
Before you fill your plate: Follow the vegan labels and check dressings and desserts separately. Most dishes are charged by weight; this is not an unlimited buffet with one fixed admission price.
Highlights: Flexible portions and a choice of hot and cold vegan dishes.

Vegan breakfast and brunch in Bonn
Choose the service, not just the venue
ESSKALATION publishes a specific weekend brunch window. Reserve that service for a slower breakfast instead of assuming the weekday lunch offer starts with the same menu.
Keep early mornings separate
This selection does not establish an everyday early-opening breakfast stop. Check a separate option when your day starts before the cafés and restaurants here open.
For a shared breakfast, decide whether everyone wants an individual plate or several dishes to compare. An à-la-carte brunch and a self-service buffet have different portion and pricing rules. Agree on the meal format before reserving, especially for a group or a tight departure time.
Plan your Bonn food stops
Save the full destination
Use the street and number from the profile when opening directions. In particular, select the Bonn branch for a restaurant group rather than letting a search result choose another city for you.
Leave space between meals
A brunch, a tapas order and a buffet plate can each be a substantial meal. Choose one main food stop and keep a café break flexible instead of turning every recommendation into an appointment.
Before a dedicated journey, check the current menu, kitchen closing time and any holiday notice. The tables record published schedules, not live opening status. Use current menu prices for the order you actually intend to make, including drinks and sides; no final bill, table availability or travel time is guaranteed here.
