"LGO" is great. There is the grocery and the pizzeria - if you go there for breakfast or lunch, you will have to order at the grocery and then there is self-serve seating in the pizzeria. They do not serve pizza until the evening (and then they no longer serve certain sandwiches and other breakfast/lunch items in the evening). In the evening, the pizzeria becomes more of the traditional go to the hostess to be guided to your seat sort of thing. That sort of explains the chaos/mayhem some of the other posts have alluded to that can happen in the mornings. However, I believe this particular entry is for the pizzeria, which is more dinner oriented.
Some tasty dishes that I have had that I would recommend:
Evil Princess Thai Chicken Salad
Gladiator Pizza
Mushroom Party Pizza (add proscuitto)
Avocado Pizza (add proscuitto)
Fish Sandwich
Cheeseburger on english muffin
The guacamole and cheese dip thingy (it's not called that, but I'm blanking) are good too - I believe it's a three dip appetizer platter of some sort.
The food here is really tasty. They also have some nice bottles of wine on their list (and in the grocery). Great place for a non-stuffy date or for a decent sized group of people (although probably not more than like 8) to share a bunch of pizza/apps.
One last thing: parking can be a real pain. I usually just suck it up and valet - it's free if you get it validated in the restaurant. Throw the valet person a few bucks - why not?
