Dear Arumugaakash, 

There is no venue for AIQ counselling, since All India Quota (AIQ) counselling was done by DGHS, on behalf of MCC, even for the state of Tamil nadu. 

Now, in case you are asking as to the venue for Tamil Nadu MBBS/BDS state counselling, then ranks invited for TN state counselling were invited on the respective dates at GOVT. MULTI-SUPER SPEICIALITY HOSPITAL, OMANDURAR GOVT. ESTATE, CHENNAI – 600 002. 

Hope it clears. 

All the best!
