If you're craving “Authentic Mexican” then avoid Santo. Sadly the food and service only consistently disappoint. The staff is unfriendly, the service is slow to non existent and the bar service is the worst I've ever encountered. Over the past year I dined there about half a dozen times but reserved judgement until now: BAD. In addition to the above, Santo should win awards for London's most tiny and pricey margaritas, avocado-less guacamole, oddly rubbery and fatty pork pibil, and synthetic like cheesey enchiladas, to name a few. If you enjoy being ignored and paying for food that tastes like it comes from a jar then Santo could be one of your favorites. It certainly isn't mine.
