baklavaci hacibaba prepares, by far, the best baklava and sobiyet in the nation. Their products are heavenly blends of sugar, butter, walnut and pistachio and will satisfy you completely.
If you are used to Greek or Arabic style baklava with honey and clover, Turkish baklava will taste quite different, however, this is how it actually should be prepared. So, please, do not question the price at all; it may sound relatively higher when compared to its Greek or Arabic counterparts. Do not claim that you tasted baklava if you have not tried baklava by Hacibaba.
...well, nothing is perfect; they sell fresh baklava that is baked daily, and in small batches, so they may run out of certain types early in the day. Try to visit this place early, especially on certain days that are considered special by Turks, e.g. Ramadan, Eid etc.
Enjoy :)
