I posted a review of Yanni's Greek taverna in Cleveland Park, but it seems to have been censored.
It's my belief that bad restaurant experiences need to be shared so that there is a reward and punishment system for good and bad places.
To give me my 'censored' take once more, and hope the owners aren't moderating this site: Tzatsiki sauce was incredibly good, thick and creamy, but the actual beef souvlaki was coronary-clogging greasy and seems to have been pan fried in its own fat. Room very small. Bread mediocre. Would not return.
