Today, I had the opportunity to revisit El Charco, following the restaurant's feedback, with the express purpose of sharing an updated review with my followers. Here's my detailed experience:

1. Service Efficiency: The service was unfortunately extremely slow during the visit, a concern that seems to be growing as the establishment expands. It appears that the staffing might be insufficient or in need of further training. Despite being only one of four patrons, it took an unacceptable 30 minutes to serve shrimp soup and pasta.

2. Cuisine Quality: El Charco is renowned for its authentic Mexican fare, but this time I was left disappointed. The shrimp soup, which previously delighted me, contained a mere six shrimps – an unexpected letdown.

3. Customer Focus: Our food experience was further marred by a photo shoot taking place within the restaurant. It seemed that the staff were more focused on the photography than attending to their customers, leading to dissatisfaction with the overall service.

4. Facility Maintenance: A disconcerting incident occurred during our meal; rainwater began to drip from either the ceiling or vent pipes, nearly landing in my soup. Such an issue raises questions about the establishment's upkeep.

Conclusion: El Charco has potential, but this visit revealed critical areas for improvement. As they continue to grow, careful planning and focus on service quality will be essential to maintain the standards expected of a reputable food venue. I hope to see these concerns addressed, but until then, I must reluctantly lower my rating.
