Answer:
Differentiation strategy
Step-by-step explanation:
Differentiation strategies seek to create higher value for their customers by producing goods and services that offer unique features that differentiate them form their competitors. This is done while trying to keep the same or similar (maybe a bit more expensive) price levels as the competition .
In this case Beach Grub offers a differentiated service while keeping their prices higher than the competition but not as high as luxurious restaurants.
