The original gyro was quite good. The lamb is seasoned and cooked very well. The spices accentuate the flavor of the meat rather than overpowering it, which is very important for meat like this. The pita bread is nice and soft--not stale or overheated. The tzatziki was great, but there was just NOT enough of it. Though it does cost $0.25 extra, I strongly suggest getting it. They don't skimp on meat portions, so the tzatziki just can't keep up. The amount of tomatoes was a little lacking too, but not really to a fault.
My sister-in-law got the chicken pita and was pleased with it as well.
I chose fries as my side, but I wish I hadn't. I believe they were frozen store-bought fries that were under-baked and heavily seasoned with season-all. Don't be me--be healthy and get the salad (sister-in-law liked that too).
Ordering online with GrubHub was easy and the food was ready on time. The man who handed me our food was very friendly and made picking up our online order quick and pleasant.
I'll be going back, but next time... MORE TZATZIKI.
