Hi we stayed at the Talayot last year and went into Forcat every night to eat. Sa Calderetta (Pink Shirts) and The Grandfather (yellow shirts) were both nice restaurants and I can remember them both doing a good steak. These are next door to each other and right down the bottom of the main road.
Also down from the Vista Picas next to the little train and trampolines I think the restaurant was called the Cala'n'Forcat restaurant a little bit more pricey than the others but the food was lovely with some unusual menu choices (Steak and Strawberries - sounds strange but was nice) also these served potatoes provided you weren't too late which made a change from chips.
Closer to the apartments and at the back of X block there was a resturant I think Giovanni's - you could go for the daily menu for about E6.50 for 3 courses (smaller portions) or the main menu which was usually served with jacket potato. Again the food was nice.
Apart from the beach we didn't venture into Blanes and I don't think there are many restaurants there. Plenty in Forcat to choose from.
One thing to watch out for the walk from the Talayots with a buggy isn't brilliant some of the paths are really narrow and you can't fit more than the buggy on them.
Hope you enjoy your hols, would recommend hiring a car and trying Cala Galdana (beach perfect for little ones) and Cala'n'Bosch - just been there in June and going back again next year.
