Buffalo Wild Wings gets takeover offer

Private equity firm Roark Capital Group has made an unsolicited offer to buy restaurant chain Buffalo Wild Wings for around $2.3 billion, or over $150 per share.

Why it's a big deal: Because Roark is widely credited with reviving Arby's, a restaurant brand that had been left for dead. Now it's trying to preempt Buffalo Wild Wings from heading down a similar path of irrelevance.
