As in any city, it depends on your tastes. You can have take-away pizza for under €5 or you can blow €500 on a full meal at a 4* Michelin restaurant.
We eat fairly well, and average under €100 for the two of us for lunch and dinner.
Italy is much cheaper than France but keep away from the touristt areas like the Trevi fountain. In a normal restaurant a pasta dish will cost 6/9 Euros, a steak will be around 15 euros and a bottle of wine starts at around 15/16 Euros upwards. A pizza 6 Euros for a Margherita and 7/8 for ones with more toppings.
Just to add, start checking the reviews here in the restaurant section then when you've decided on a few check out the menus on their website that way you can also see the prices.
I was in Paris in August and was warned about prices. I allowed €150 per day for myself and my son. I ate out for both lunch and dinner and came home with money. We were staying in Montmarte so we were away from the touristy areas. Rome is which cheaper, I usually €100 per day there again for myself and my son and never ran out. However as suggested depends if you want to splurge or not. I usually have light lunch and a good dinner usually with dessert.Edited: 11 November 2012, 12:12
