I had a late flight with a low cost company from Terminal 2. The food at the restaurant was very expensive, even more than in London (a slice of pizza and a small bottle of water cost 30 TLR, so more than £7) and there is no wifi, which is really unacceptable for an international terminal. The only place to get wifi is the lounge, but you need to be a customer to get the password from the staff otherwise they just ignore you.
