I thought (based on another article i read last week) there were now three locations, but two were closing/closed due to lease disputes with the property owners.
My opinion is Rays Hell Burger was cruising along OK but due to the Obama visits it achieved so much notoriety (in DC area) that the landlord demanded some insane amount of rent when the lease was up. Without the Obama visits this would not have happened. The owner Ray refused to accommodate the greedy landlord. He can always open elsewhere with a better lease
I hope so. Those burgers are soooo good!
