nutritional info for Gyros?

fabafter5

I'm finding that the nutritional info for gyros is all over the place. Not sure what to go with! I get mine open "open" aka minus the pita. My fave Gyro place boasts that their gyros are 348cal and 6g of fat. This seems impossible to me. I found a pitaless gyro in the database but it says the carbs are 30g for lean meat, tomatoes, lettuce, onions and tatziki sauce.

Any resources for a true count?
