Restaurante El Tambor is most consistently praised for its elevated setting and wide views over the valley, Antigua, and the surrounding volcanoes. Reviewers frequently mention the scenery, especially around sunset, as one of the strongest reasons to visit. The atmosphere is generally described as relaxed and scenic, making the restaurant as much about the setting as the meal itself.

The food receives mostly positive feedback, particularly for traditional Guatemalan dishes such as soups, fish, caldo de gallina, guacamole, sauces, and coffee. Several reviewers describe the food as tasty and reasonably priced, and many also mention friendly or attentive service. The overall impression from most reviews is of a casual place serving local food in a memorable location.

There are, however, some reports of inconsistency. One reviewer described very poor service and food problems during a hotel stay connected with the property, including a room issue, lack of water, an uncomfortable bed, and undercooked chicken. Another reviewer mentioned slow drinks and disappointing nachos. Access can also be a consideration, since reviewers describe the road as winding, narrow, or rough. Overall, the views and traditional food are the strongest recurring positives, while service and access appear less consistent.
