I'll just say this up front: this restaurant has excellent food and service, regardless of what you eat. They offer a good amount of gluten free items, and are super friendly about menu questions. Our waitress went back and forth twice to verify answers for me.
They make GF pancakes and killer Huevos Rancheros (you can ask them to skip the tortilla chips if you don't want any deep fried food).
My food came out with a large toothpick marker and a little "GF" flag on it.
It's a little on the pricey side overall but that includes the entire menu. Given the service and the quality it's worth it. Bottom line: there didn't appear to be a "Gluten Free" tax.
NOTE: I didn't ask about separate kitchen space, and I never eat fried food in restaurants, but now I'll know to ask...
