Arabica is both good and average, depending on your motivation. Service is far from slick, but they are trying to do their best with a menu that stretches from from Athens via Yerevan and Old Jaffa to Cairo. We were there on a Tuesday lunchtime, and the trains shook the place as they rattled overhead - rather a nice touch we thought, being both slightly alarming the first time you feel and hear it and ultimately strangely comforting once acclimatised.
Covering such a large part of the gastronomic globe is a challenge they meet very well - a Lahmacun (Armenian pizza) with lamb, tomato and spices was superbly done as was a large Lamb Kibbeh, crunchy yet beautifully moist inside.
Their version of Hummus Kavurma or Schwarma (depending on who you are talking to) was good, but the lamb was barely tepid on arrival. Home made Tarama pleased with its authenticity and slices of yellowfin tuna came fresh and raw with a delicious dressing.
The house pickles and smoked almonds are no more than average, but their spicy lamb kofta is deliciously plump and and full of flavour.
Arabica is certainly worth a visit if you're in the area and love meze and all things mid eastern, but it's not one for a sole pilgrimage. They have brought together a few interesting ideas in a cool space, but on our day I'd say the service was amateurish at best, those looking after us were definitely under instruction and initiative was no where to be seen. We didn't drink but the wine list looks well thought out and should please most palates.
In summary certainly worth a shot for the sheer breadth of taste and quality of cooking.
