Hi there, welcome to erbil, it is safe and sound here, the ramadan will be over after about 20 days, you can enjoy a good german beer at the german beer garden or hit Palmera for partying, in the day time just to know your way around, head down to the city center to see the citadel and have a look around just in case you need anything to buy, things are cheaper in the city center, in case of emergencies pay these hospitals a visit ( Rozh halat emergency hospital and Rozh awa emergency hospital), according to your location.
Regarding restaurants, most of them just charge for the food, except a few restaurants in 5 star hotels which have minimum charge.
There are a few gyms like (esporta) near Naz city .
Let me know if you want to know more
