Review: I'd never eaten at a "vegan collective" but was eager to try it after reading reviews here on happy cow. I did my best to follow the instructions and call between 4 and 6:30 to make a reservation, but I couldn't find a phone in time, so we just turned up around 7:15 (they open for dinner at 7pm) and hoped for the best. The woman said they had enough food and could squeeze us in. After asking if we knew how it worked (not really, we replied), she explained that the all-volunteer staff makes the food, we pay according to our ability (between 7 and 10 euro), and when we finish eating, we bus our own tables. OK! The atmosphere was relaxed and homey, with music thumping and people hanging out drinking and chatting on cozy couches and wood tables. Nice low lighting and interesting art on the walls. We paid for our meals, then got our soup and paid for our beer and wine (2.50 each; the wine was great and the beer was organic). The woman said she'd call us when the main course was ready. That night the soup was borscht; the main course was sushi (seitan/walnut--what a fabulous revelation!), served with roasted potatoes and a small salad. I loved the experience-- the food, ambiance, and novelty of it all. I also like supporting grass-roots cultural organizations, and really appreciated that De Peper is 100-percent vegan. I'd go back in a heartbeat and highly recommend it to others. In the hallway just before we left, there was a sign saying "free books--please take!" Rummaging through the stack, I found a brand-new and very popular vegan cookbook that I was happy to schlep home. Double score!
