I first went to Vefa Bozacisi 12 years ago. Before leaving a review I always read the negative comments to see what I can relate to or what I can defend. Let me say this: There is a tradition to go to the kuruyemis shop across the way, like 3 steps, and take freshly roasted chickpeas to top the Boza. Somebody wrote even that they don't know what is so special. Well there is a reason that tradition stays. This place was founded by an Albanian immigrant. He worked very hard to adjust the recipe for Boza that was being sold in Istanbul. It was watered down apparently and not sweet enough or creamy. He figured out a way to make the fermented beverage sweet and creamy and refreshing even... I have to say the taste has changed. I really hope that whatever has happened will stop. In my mind I think perhaps the tourists prefer it sweeter like its become, but I dont know. On the other hand, I have always known this place to be a "try it" place- where ppl know they may not like it but have a real desire to try it due to it being such a unique flavor. The price is going up and up but I can't say that it is unjust. This place has always been good to the customers when it comes to cost. They have had the least amount of increase in cost time and time again. I have never left a review for a place already with SO MANY reviews. This is a good to place in a small little tour I give to my guests and that I bring groups I gather on social platforms to, along with the soda pop shop on the same road, the historical area all around it that include historical mosques (of course), and other small little wonders. It is always worth a visit inside in my opinion. I hope everyone working here gets the encouragement they need to be a little happier these days forward.
