Dinner before concert at San Diego State
I live in the college area and unfortunately most of the food is directed at the starving student crowd (overstuffed burritos and giant cheap pizzas). There is a good sushi place on El Cajon at 60th called Toshi which would be my number one recommendation based on food and locaation. If you are not up for sushi and want to stay casual, there's an little Italian deli called BMH (http://www.bmhitalian.com/index.php) which has great sandwiches and good pasta, but is an order-at-the-counter type of place and doesn't serve any alcohol. Antica Trattoria (http://www.anticatrattoria.com/) in La Mesa is a favorite on this board and is probably the best restaurant in the area, but it is a little bit of a drive from the stadium.
sorry I am unfamilair with Wilco..so not sure what you mean 'chowish' but the Kensington area is great.. Kensington Grill and I believe its called La Boheme..something like that has opened just accross the street. also down Park blvd alot of options..these are not too far away...

They have a great Happy Hour M-F- all appetizers 1/2 off. We usually get the "sampler" of beers brewed there. When you leave, it's pretty much a straight shot to the Venue. (no more freeway)
