i've been to the Tempe MBFGR three times for lunch in the last two months and used to go to the Scottsdale location 3-4 times a year when my office was two blocks away.
the food is always good - love the Greek fries with the lemon-oregano sauce, and the flaming Saganaki is very good too. i always have the gyro pita, because it is just so damn good, and reminds me of every little Taverna i stumbled into in Greece and the Aegean Islands. the tzatziki sauce varies between enough and not-enough garlic, but i always get an extra cup of the stuff,,,, nectar! Last time we ate there, Liz had the feta burger and she raved about it for a week.
the waitrons and staff are always good and always friendly - i don't know how they do that, but it's true
