The investment appraisal analysis for the proposed project at Blackfriars restaurant reveals a negative return of £8596 and an internal rate of return (IRR) of 10%, which is lower than the industry average. This outcome suggests that the company needs to focus on other proposals that can enhance profit margins. On the other hand, customer attitude towards dining services at Blackfriars is positive, and with rising disposable income, people's lifestyles are changing, leading to an increase in restaurant visits. It is recommended that the restaurant unit explores its business area further.
