Zizzi's is the restaurant I most often choose to visit and go there for regular catch ups with my girlfriends. The reason being that they generally always have a voucher offer, which either entitles a second person to eat for £1 or is two courses for £10. See their website to print yourself one. http://www.zizzi.co.uk/
It works out to be quite good value with the voucher offer, especially the main course for £1 deal. Zizzi's is a chain restaurant, found all over the country serving up Italian dishes. In Cambridge, it's located right in the heart of the City, on Regent Street by Parkers Piece.
Some of my favourite dishes include; 'Strozzapreti Pesto Rosso' (chicken with creme fraiche and red pesto), and the 'Linguine Gamberi' (linguine with tomatoes, prawns and chilli). I like to order fine green beans as a side too and they come drizzled in olive oil with rock salt. They obviously do a pizza and calzone selection as well as a meat and fish menu (not usually included in the voucher offer). Dessert-wise, for anyone who loves chocolate, I totally recommend their chocolate melt which has a warm, gooey middle, however the 'Torta Cioccolata' and 'Pannacotta' are also great.
I've never been disappointed when eating there and considering I go there so often, this means that their food and service is consistent. They also have one of the nicest rose wines I've had around town; though I like my wine more sweet than dry, which is not to everyone's taste. If you have a similar preference I recommend the Zinfandel.
Reliable restaurant with filling Italian dishes. Do not visit if you're one to avoid refined carbs like bread and pasta!
