Delphi (they spell it Delfi) is found in Lilian Ngoyi (Windermere) Road in Morningside, and is housed in an unprepossessing building just off the road. When we visited, the place looked a little like the temple of Apollo with its tumbledown columns - the wind had recently blown down their patio roof.
Perhaps fortunately, I had forgotten my camera, as the interior is very Greek-kitsch, with lots of checked table cloths, faded posters, chipped plates on the wall (memorabilia from a big plate smashing night?) and tastefully arrayed plastic grapevines.
The wine list is on the minimal side, but luckily I had come prepared with a bottle of Waterford Rose-Mary in the boot, and their corkage is a very reasonable R15.
The place seems to do very well out of repeat business, which speaks well for it - there was much hugging of the owners, and plenty of people seemed to know exactly what they were going to order. It's a small restaurant, with only room for 6 or 7 tables.
We ordered the meze platter for starters, as well as a portion of squid heads. The platter was the highlight of the whole meal, and featured fantastic eggplant, saganaki, kofta and dolmades. The squid heads were decent, but not as good as some.
The main course was less inspiring - my lamb shank kleftiko was very tender, but a little flavourless, with a thick, sticky gravy which did not add greatly to the experience. The side dish of rice was also cooked with frozen peas and carrots, a pet peeve of mine. The chicken souvlaki was served in a pita and was fairly good, but also lacked real depth of flavour, focusing mainly on garlic, with few other tastes coming through. I felt that it could have used more tzatziki, lemon, dill or mint.
Dessert - the halva and icecream was delicious - I need to make this at home, but the galaktoboureko was also a little plain. The less said about coffee the better.
Overall - it's a cheap and cheerful spot, with simple, hearty fare on a road with several other restaurants. If in doubt, pop in for the meze, and if nothing else takes your fancy - go for a roving dinner.
