Time Out says
A few vegan and vegetarian restaurants have sprung up along Kurabiye Sokak, close to Taksim Square. The most buzzed-about seems to be Zencefil, but while its garden is pretty and the atmosphere appealing, the prices are high for what you get. (Order a courgette quiche and that’s all that will appear on your plate; no side salad or sliced fruit, just a slab of quiche). Instead, cross the road to the less fancy but equally vegetarian-friendly Parsifal, a small, comfortable spot with wooden tables and chairs, random frames decorating the walls and a laid-back vibe. The menu is 100 percent vegetarian, the prices are very reasonable and you can enjoy a beer or glass of wine with your meal. The cooking can be a little hit-and-miss sometimes, but it’s generally a good dining option for a relaxed veggie lunch or dinner. Call beforehand if going for lunch; occasionally they close in the afternoons. Alcohol available.
