Hi Foxes,
What kind of food do you like? My favourite restaurant in Gumbet is Seray Zetas, they do wonderful authentic Turksih food at very reasonable prices. Other good restaurants are Cafe Columbia, Windy Bay and a new restaurant, which I haven't tried yet but has excellent reports is Jack's Place.
Good all round bars are Smilies, Chico's, Leo's, Corner Bar, Aloha, and Atlantis. If you want busy club type bars then X-Bar, Shakers and Central Bar are the popular ones.
