The build-up cover approach for forecasting beverage revenue is handled in a manner similar to that for projecting food revenue. The appraiser first looks at the percentage of the business that will be generated by in-house guests and the percentage that will originate outside the property. If the hotel lounge has any degree of success, a substantial portion of the beverage revenue will come from patrons who are not hotel guests. In addition to the demand generated from the beverage outlets, a certain amount of beverage revenue originates from liquor consumption by in-house restaurant- goers.
