I just got an email from a restaurant affiliated with the same restaurant group as Mad Mex in Pittsburgh called Kaya. They have a special vegetarian prix fixe on the third Wednesday of each month featuring fresh produce for $39, with optional wines for $23. I might have to leave Cowtown for the Steel City to check it out.
Also, I see the Refectory in my distant future. I'm kind of an amateur psychic that way.
