Yes, a lot of people say look for the egg, but I wonder if that is a good barometer because the egg is usually served towards the end . Also, some say try the anago, because it takes more preparation and is more difficult to shape into beautiful sushi. I used to order anago first so that I can see the skill of the chef, but since anago is one of the most heavy sushi, it's not really a good plan. Now, I just try the gari (the ginger sides), because better places take the time and effort to make good gari from scratch. Regardless of price, the majority of places buy the gari in bulk, and I think this shows their laziness.
