Located in a unyuppyfied section of East Dallas, Z Café has a funky, friendly divey feel that makes it a fine escape from the workplace grind. There's lots of Parthenon posters and white-and-blue flags to remind you it's Greek. The daily lunch specials, which run about $5.99, are taken off the café's menu of gyros, sandwiches, dolmas and such. The lamb gyro is only $6.95. Then there's the signature Z burger (feta cheese, grilled onions and jalape?os), which is a perfect start for that long afternoon nap at your desk. To sleep better, take the boss.
