Microbrewery Craft is on Alexandras (virtually across the road from the Panathinaikos stadium). The beer is nothing to get excited about, but the food is very good indeed. Almost across the road from it there's a very good Greek restaurant (not taverna) called Agora. And last time I went I visited a very good newly opened Spanish (actually chiefly Basque) restaurant called Mayor in the eternally trendy suburb of Kifisia (on Harilaou Trikoupi...but that's the Har. Trikoupi in Kifisia, not the one in the city centre!)
