I definitely want to go sightseeing and minimize the cost whenever possible. Trips on the water are fun, and I can do some writing while I'm at it

.
Do you all have suggestions for any inexpensive restaurants or places to grab some food?
I'm ridiculously excited but likewise nervous. Since I'm not familiar with the language, I'm slightly terrified of getting lost or worse, doing something that I didn't know was "taboo" (e.g., wearing shorts

)
I leave this Saturday, so if any of you all have any other suggestions, please let me know!
By the way, I'm flying Onur Air from Kayseri to Istanbul. Anyone know if it's a relatively safe airline? Any baggage restrictions? I try to access their website, but it's all in Turkish with some relatively attractive woman with a headphone piece from the 90s.
Thanks, FT
