Hi
We got back from Sidari Monday just gone family of 4 and went to the waterpark for the day. The apartments look lovely and the pool is great but very deep at one end. The food in the waterpark is lovely and you could get a club sandwich with chips for just short of 6 euros. We ended up going back to the waterpark on Saturday night as they have a BBQ with greek dancing and entertainment and then they open the slides about 11.30pm for half an hour. It cost 11 euros per adult and 6 euros per child and the food and entertainment where fantastic so would defo recommend.
If you go on the main strip you can get a main meal for about 6 euros, pint of lager is 2.50, shorts are about 4 euros and short drinks about 2 euros.
However if you go down the track from the waterpark towards the beach not towards the stripe, when you get to the end and are at the sea turn right and there are some nice restaurants down there including a traditional greek taverna. If you past the taverna which is called "El Grecco" you will come to the Perros pool apartments and they do a 2 course meal for anything between 6 and 8 euros and the food is fantastic we spent a lot of time in there for our meals and they are fantastic with the kids.
Hope this helps and have a great time. We are looking for flights now to book to go back again next year so I can't wait.
