Had dinner there last night. Prices for everything...

Had dinner there last night. Prices for everything are up there . 18% was added to our check, party of 3????? It's usually done to 6 or more or separate checks. The bill was presented with a fold over the amount . The fold on top had a blank space for additional tip and suggested amount percentages. We almost left 36%, and our friends almost did too. It's dim lit and if you don't really get out a flashlight and examine your bill, you'll be taken to the cleaners. How deceptive and crooked way to treat visitors. No
