Any ideas of where to go?

Somewhere nice and romantic, preferably central or south sheffield.

Nice and classy ish but not too expensive I'm not made of money!

Haha
Cheers

Try Antibos Italian Resturant In Town Very Nice And Romantic

Try Maranello's on Ecclesall Road, not too pricey and you can see into the kitchens and watch them preparing the food, it really is excellant and the Garlic bread is to die for!

Also where ever you do end up don't forget to drop it into the conversation that you are out on your anniversary and try and be a bit cheeky and get a free bottle of fizz or something thrown in. It works - sometimes lol. But you've got nothing to lose.
