Patisserie Valerie is Falling Down

I always knew Patisserie Valerie being in Soho, then it expanded everywhere, I thought it seemed unsustainable.  Then their products were all over Groupon, I bought a Groupon for a meal at one of their sister restaurants, Philpotts.  Then they made the news and I cancelled the Groupon as soon as I could...  I still wonder why they had to expand...
