Horizontal offers, among others, vegan seitan and tofu burger. I preferred the seitan burger, the tofu burger smelled to fishy in my opinion. Cheapest burger I ever had. Really good!
Unfortunately they had no cake or sweets, or were out of them.
They offer just soy milk and some juice as drinks. But in the loft project are other bars, were you can get your drinks.
You have to enter the loft through a backyard. Horizontal is more a kitchen, than a restaurant. Easy to oversee, but its in the ground floor. They have no seats, but inside the loft are many seats possibilities available. Alternative and creative atmosphere.
