Can anyone tell me how many 'Lex' firms do we have in Delhi/Mumbai?

5 within a radius of 200m of my office in Defence Colony

No way its that less

Does any of those also happen to have Luthor in the name?

No - there can be only one Rajiv Luthor.

It's time to use REX to denote that the firm is ferocious firm like a Trynasourus Rex :-D

Inspired by Lex, Legally India should change to Lex India :)

Have you visited Safdarjung Enclave, Jangpura, Greater Kailash, or Defence Colony lately?

It's a GLARING OF Lex Firms!

Lawyers are, indeed, rather unimaginative.

because it rhymes with.. fex?
