A full bar is the primary service mechanism for clubs that offer alcoholic beverages. In many clubs the main bar is the second most dominant element on the floor after the main stage, and in some cases the main (or satellite) stage is built into the bar. Clubs can derive large percentages of their income from drink purchases. For both Rick's Cabaret and VCGH, Inc., service revenues were the single largest revenue source, with sales of alcoholic beverages second. VCGH earned 18% more and RICK 27.5% more in service revenue than alcohol sales. The amounts are closer when food "and" merchandise sales are considered, with RICK reporting a smaller gap between the two revenue sources relative to VCGH. Upscale clubs that offer food can have or bars for buffet service. Otherwise, food orders might be taken at the main bar or by waitstaff.
