If you visit the info desk in the convention center which I think is on the 2nd or 3rd floor they can give you a map of the area that includes the nearby mall (a couple blocks away but easy walk through the lovely park) that has every kind of food plus some nice salad places, sandwiches etc. less expensive. Works well for lunch.
Taxi is probably the easiest way to get around to restaurants at night. Ask at your hotel for restaurant recommendations as There are lots to choose from depending on your tastes.
Have fun!
