my mum in law wants help with where to go for her 60th. Will be lots of us all ages want good food and music, Is there a greek mezzi or anything like the bistro live (the ones I know are in Notts)

There's a place called Mad Greek in town.

I've been myself, it wasn't my cup of tea because i didn't really like the food but I'm sure other people would.

The place itself is fun for groups, they do all the dancing and plate throwing.

Sorry I don't have a clue of it's address or phone number.

After a quick Google, I found the exact details shellie requires:
