I'll keep this short and sweet: my first visit to FAT Lamb Kouzina this afternoon was phenomenal. In fact, it exceeded my expectations even--which were high, mind you. Had their Bifteki Gyro and 'Tiropita' Pie. Both were perfection. Suffice to say, I'll be back a couple times a week and won't rest until I try the whole menu. Incidentally, the owners were extremely warm and welcoming. Great addition to the Yorkville neighbourhood.
UPDATE [6/9/2017]: No surprise here, but my next two visits came only days after my first. And yes, each was better than the last. This place is the real deal.
