Essex has tapas style dishes, so small and medium plates. I would recommend getting 3-4 per two people. It's in a great location to people watch and sit outside. We had a ninja sushi roll, bang bang grouper, chicken skewers, and veal meatballs. Everything was very good, but the grouper was especially great!
The only draw back to this restaurant was that it was a little expensive for what you got. I'd still recommend going, but it's about $15 per plate, so with drinks it's definitely a more expensive night out.
