Grilled Teriyaki (259 E. Broad Street) has closed down, making it the second short-lived Japanese restaurant (remember Tokyo Sushi Rock?) in that space since Mellow Mushroom moved over to Clayton nearly a decade ago. Renovations have already begun to make room for a new Puerto Rican restaurant. I spoke with the owners and they told me that the new venture should be open in about a month. I don't believe Puerto Rican cuisine is currently offered in Athens, so this restaurant should be a nice addition to the downtown lineup.
