Taylor’s is a popular restaurant that offers customers a large
dining room and comfortable bar area. Taylor Henry, the owner and
manager of the restaurant, has seen the number of patrons increase
steadily over the last two years and is considering whether and
when she will have to expand its available capacity. The restaurant
occupies a large home, and all the space in the building is now
used for dining, the bar, and kitchen, but space is available on
the property to expand the restaurant. The restaurant is open from
6 p.m. to 10 p.m. each night (except Monday) and, on average, has
24 customers enter the bar and 50 enter the dining room during each
of those hours. Taylor has noticed the trends over the last 2 years
and expects that within about 4 years, the number of bar customers
will increase by 50% and the dining customers will increase by 20%.
Taylor is worried that the restaurant will be not be able to handle
the increase and has asked you to study its capacity. In your
study, you consider four areas of capacity: the parking lot (which
has 80 spaces), the bar (54 seats), the dining room (100 seats),
and the kitchen. The kitchen is well-staffed and can prepare any
meal on the menu in an average of 12 minutes per meal. The kitchen,
when fully staffed, is able to have up to 20 meals in preparation
at a time, or 100 meals per hour (60 min/12 min × 20 meals). To
assess the capacity of the restaurant, you obtain the additional
information:
Diners typically come to the restaurant by car, with an average
of 3 persons per car, while bar patrons arrive with an average of
1.5 persons per car.
Diners, on average, occupy a table for an hour, while bar
customers usually stay for an average of 2 hours.
Due to fire regulations, all bar customers must be seated.
The bar customer typically orders one drink per hour at an
average of $7 per drink; the dining room customer orders a meal
with an average price of $22; the restaurant’s cost per drink is
$1, and the direct costs for meal preparation are $5.
Required:
a. Given the current number of customers per hour, what is the
amount of excess capacity in the bar, dining room, parking lot, and
kitchen?
b. Calculate the expected total
throughput margin for the restaurant per day, and month (assuming a
26-day month).
a. Given the expected increase in the number of customers,
determine if there is a constraint for any of the four areas of
capacity. What is the amount of needed capacity for each
constraint?
b. If there is a constraint, reduce
the demand on the constraint so that the restaurant is at full
capacity (assume some customers would have to be turned away).
Calculate the expected total throughput margin for the restaurant
per day, and month (assuming a 26-day month).
Taylor has obtained construction estimates. To increase the
capacity of the bar to 80 seats, the dining room to 120 seats, and
the kitchen to 25 meals at the same time would cost $250,000, which
Taylor could finance for $5,000 per month for the next 4 years.
There would be no change to the parking lot. Given your analysis
above, prepare a brief recommendation to Taylor regarding expanding
the restaurant.
