Sultan Bakery in San Jose has Katayif available every day, during Ramadan only. It’s a very addictive greasy stuffed pancake. Tastes like they added rosewater to the batter. It’s excellent, and worth a trip. They make them in the morning, then keep them in the refrigerator case: I recommend heating them up in a convection oven for a few minutes.
You can get cheese filled, walnut filled, or hollow. The hollow option is for those who want to add their own home-made filling. For the filled ones, it’s $12/pound, which is about 7 Katayif. They had plenty on hand at 2 PM, but there is a possibility they could run out later in the day.
