Gentlemen:

We are in receipt of your letter of January 24, 2011.  As we discussed in our meeting earlier this month, we value the input of all our shareholders.  It is in that spirit that we agreed to the meeting and offered to continue the dialogue.

We disagree with a number of assertions in your letter, but in particular with the suggestion that the Board lacks a sense of urgency with regard to improvements at Red Robin.  As you know, we reconstituted our Board with a new group of independent and experienced directors.  This new Board, together with Steve Carley, our new CEO, and the Company’s senior executive team, immediately undertook the task of evaluating and developing strategic and operational improvements designed to enhance shareholder value.  This new strategic initiative, known as Project RED, was initiated in late October 2010, well before Oak Street filed its Schedule 13D, and reflects the strategic, financial and operational priorities of the new Board and management team.  As part of our year-end review, in early January we chose to share some highlights of the strategic initiative, while committing to announce further details in connection with our fourth quarter earnings release in mid-February.

We have set ourselves an aggressive timetable for this strategic task, and while moving fast, have been working to incorporate the views of multiple key constituencies including our shareholders and franchisees.  We look forward to sharing with you and our other shareholders the details of Project RED in just a few weeks, and look forward to hearing thoughts from all our shareholders then.
