Ess and Bench (in its current iteration) will never be trendy, and Calabria seems to be following along the same path, it looks like they have an identity crisis and haven't even opened yet.
Ess n bentch is an idea like chocalate ,its not that trendy , since this specific street where ess en bench is located is highly traffic area , so like 50 percent of the year when crown heights is packed with thousands of visitors its a perfect place for a fast in and out low cost option to grab some food , makes sense to me just like chocolate in a meat version
