Baci evacuation on Friday???

Does anyone know what happened on Fri evening at Baci Restaurant in Westwood? We were having dinner there, when suddenly I- and the rest of the patrons- began coughing and choking uncontrollably and had to evacuate. Police, Fire and EMT arrived. I've been calling Westwood PD since and so far have NO idea what caused the coughing & choking.  I think I have a right to know!
