I placed my order and asked if they cooked the eggs in butter. The waitress very cheerfully said they cooked everything in clarified butter. I said I'm completely lactose intolerant. We stared at each for a few beats before we had a detailed conversation about how the eggs are cooked. She said the eggs were cooked on a separate griddle and she thought they could clean the griddle before cooking my eggs and that she would check. Time passes... and she brings us our food. So now we didn't have a choice about just leaving to eat somewhere else. Strike one. I asked her if the eggs were cooked with oil, and she said, "Yes, they were only cooked in oil, but you know that once butter is clarified it's totally dairy-free!" Strike two. She later said the chef said lactose-free and she messed up, but I still didn't eat the eggs. I do not trust a kitchen that is operating under the delusion that clarifying their own butter makes it lactose-free, that is not in line with food safety standards.

If they cook everything in butter they should advertise it, that would draw plenty of people in and let people who can't digest dairy like myself know to steer clear.

Edited to respond to the cafe's response: Your time would be better spent updating your website and your menus to accurately reflect the fact that butter is on everything in your kitchen. Crappier restaurants than yours have figured out how to produce one or two menu items that are dairy or gluten-free. You've just decided not to. That's fine, you get to make that decision. Kindly let everyone know so that some of us don't have to waste our time or yours.
