Should it look premium if your prices are mid-range?
No, if premium means a voice and a gold that the bill on the table cannot support. It should look cared for: readable type, a photo of the venue and a mark that matches what you charge. Put the average bill next to the brand proof. If the piece promises a dining room that is not yours, the ornament goes. In the sierra it is designed like a city hotel and the guest complains about the price on the way in. The brand lied before the bill did.
A visual line at the level of the bill: mark, colour taken from the room and a menu without extra ornament. The sheet crosses out the effect that lifts the promise above the price.
