I've already sung the praises of another Real Greek venue, at Covent Garden, because of its fantastic venue, but I think the Marylebone branch is worth mentioning too because of its location. Chi chi Marylebone High Street has plenty of decent eating options but you probably have to queue for them (yes Relais de Venise and Providores, I am pointing the finger at you!) which we all know winds some people up. The Real Greek is both bookable and reasonably priced, two big plus points for this area. Our group of 7 didn't drink much in the way of booze but we put away an awful lot of food: we ordered about 30% more than the waitress recommended, finished pretty much all of it, rolled out clutching groaning bellies, and paid a measly £28.50 a head for the lot. The waitress was patient, efficient, friendly; the restaurant decor bog-standard; the quality of food good; and yes, I think it is authentic, certainly compared to Greek tavernas in the backwaters of the Greek Cyclades! Very good value for money and a great choice for groups around here.
