We went to the Burger Stop almost every day while we staid at the Amarte Hotel next door (we staid there for about 2 weeks).
The food was great and the prices were cheap, especially considering that the restaurant is located within a resort location.
The menu was in both Spanish and English, thus, not being from a Spanish speaking background, we were still able to order with no problem.
The staff were also very friendly. Since we visited the Burger Stop so often (sometimes more than once a day), after some time the manager started giving us discounts of 10% for our orders.
I would recommend this place to anybody staying at Amarte or nearby hotels, or even just anybody passing by. Happy!
