Sure, we can do code reviews! It's usually helpful to provide your
code in-line, though, rather than linking to pastebin.

You're using Python 2, as evidenced by the print statements. So don't
do this, ever:

> def emp_age():
>     """displaying employees age"""
>     age = input("Enter age: ")

The input function is extremely dangerous. Everywhere else, you use
raw_input, which is correct.

This is an old-style class. It's better to explicitly subclass object:

class Bar(object):

> class Beer(Bar):

Not sure why you're doing this. Firstly, you never use your Beer
class... but secondly, your Beer isn't a special type of Bar, it's a
quite different thing. When you subclass, it's usually helpful to
follow the Liskov Substitution Principle:

Think carefully about your class hierarchy, because it defines all
sorts of things about your code. Be sure you're happy with it before
you code up too much else.
