Costa Rica restaurants for rent are specialized commercial spaces with various installations specifically for serving food. Of primary importance are the proper facilities to operate a commercial kitchen. Adequate ventilation and access to propane are often high on the list of requirements.
Layouts can vary drastically as some restaurants are essentially open air in structures like ranchos (palapas), or have an indoor kitchen with outdoor dining, or they may be traditional, fully air conditioned spaces.
There are also drive through type constructions for serving fast food.
Lease inclusions will be highly variable for restaurants as some are just the space with essentially nothing whereas other have everything including full kitchens installed and perhaps even silverware.
Make a careful study of what is included and think about your guests as well. Space for signage, adequate parking, visibility from a major road, vicinity to residential or commercial areas are all important to consider.
