At Vadistanbul, sushi is at the Sushi & Spice branch inside the mall. It suits a meal combined with shopping on the Sarıyer and Ayazağa side. From the menu you can choose sushi, sashimi, soup, udon, noodles, rice bowls and hot chicken or meat dishes. Vadistanbul is not an open-buffet branch. For the unlimited lunch buffet, look at Özdilek Park, Maltepe Park, Marmara Forum or Emaar Square. Seating is usually walk-in. A short note is enough if you are planning a large table on the weekend.
