You could do some shopping on Market Street or around Deansgate, there’s a lot of great stores and stuff to see there. There’s a science and natural history museum that’s cool if you’re interested in that kind of stuff. Also, when you’re inside it, you can overlook where they film the soap “Coronation Street,” and see the set.

Hydes brewery gives tours, I’m pretty sure you have to sign up in advance for one. They show you how they make their beer and also let you try them for free!

If you like indian food at all, visit Rusholme’s Curry Mile, there’s a bunch of great restaurants there – Lal Haweli is a great one.

There are also a ton of nice clubs and bars your could check out. That’s about all I can think of at the moment, but I’m sure other people will have lots of great suggestions. Have fun, Manchester is an amazing city!
