Out of interest went into the Park Cafe for a bit to eat couple of weeks ago.
I can confirm that the staff are pleasant and polite, and as as far as I could see they were attentive and efficient. Yes, the single toilet is clean and there is plenty of bog roll and hand towels.
The menus are clear and concise, and all in English.
The staff all speak English and its location is good, right next to the marina.
Had a karisik meze and some kalamari tava to begin. Meze was poor quality and the Kalamari got sent back as the batter was overly salty (the waiter tried one and even he couldn't disguise the look of yuck on his face!)

.
My friend had levrek which came up fine, nothing special, but no major issues.
I fancied some dead animal so had a karisik izgara. Half of a pretty bland adana kebap and three small ribs of what I had to assume were lamb. Well presented but not really worth the 15 or 16YTL it cost (can't remember exact price but in that region).
The final bill was about 45YTL and all we had to drink was water and a couple of cokes (this was after complaining and getting a reduction due to crap food). They did make an effort to rectify things, free fruit and coffee etc but I'd rather have had a decent meal.
All in all an eating place I
won't be returning to and I would recommend others to give it a wide berth also. It's customers appeared to be mostly tourists, I didn't see any locals I knew or anyone who looked to be Turkish.
