What an odd question..but yes and cheese and onion and ketchup and beef and spicey ones too.İs this a crucial factor in whether you come here for a holiday or not??:o)

iv been before i searched high and low it put a damper on my holiday cause i love them

You could always take some with you - just to be sure.....

There are supermarkets all over Turkey where you can get crisps of all flavours.

I think I saw some of them in the corner market in Sultanahmet around the block from our hotel. However, if not having them reduces your pleasure in visiting Istanbul I would bring a few bags with me. It isn't like they weigh much. (I bring canned ham with me to Turkey so I can have an occasional ham sandwich).

They have Pringles in Turkey with many different flavors however I cannot rememeber seeing salt and vinegar...however I know they have similar to sour cream and onion...my fave..

but as pringles are imported they are expensive..

They also have Lays brand chips..with many flavors including BBQ, ripple etc...

also Dorito chips too !!

there are some turkish brands as well

Pretzels are also good..try Kraks...( cracks )

I've been here two years and I have never been able to buy a packet of salt and vinegar crisps. Tomato? Yes, and the other flavours in the posts but not Salt and Vinegar... if you have specific location I'd be interested to know...
