not sure about Greek, but there are several girls reviewed on here that do BBBJ.  Tania, and if you can find her, Rebecca TJTJ.  best if you email and get the personal treatment, not the bar treatment.

At any bar YMMV for BBBJ ask ¿Chupa sin condón? for Greek ask ¿Hacer in el ano?  Greek is not my thing but I did ask DiAngela at CC and she said yes for $20. extra.  Most of my amigas are flaquitas with anos piquitos.
