First of all, I must confess that much of this discussion is cracking me up.  I just recently moved to Oakland and my apartment is literally right in the heart of the Temescal.  More specifically, it is directly above the intoxicating aromas and rather tasty treats of Bakesale Betty's.  Yeah, I guess I should have expected things like this happening, but coming from Arcata (which, unless I'm wrong, isn't home to anyone else on AN), it still makes me smile to think that much of the AN community is, in fact, part of another community that I know well.

Anyhoo, I too heartily recommend Bakesale Betty's for both baked goods and their rather divine fried chicken sandwich (which is so good I may have to pick one up before meeting everybody at the game on Saturday).  For a more traditional, sit-down meal, you cannot go wrong with Dona Tomas.  Yeah it may take awhile, but they sure have some great food.

Also, for whatever it's worth, if you and your wife feel the need to check out a separate spot for dessert, I truly cannot say enough good things about Fentons Creamery (also off of Piedmont Ave in North Oakland).  It's an ice cream parlor, so don't go if either of you are hankering for some tiramisu or creme brulee, but it's easily one of the most enjoyable places I've been to since I moved down here.  The vibe is fun and relaxed (although the place has been packed every time I've been in, making it also rather loud) the ice cream is amazing (their sundaes being a particular favorite), and in a nice A's-related touch, Marty Lurie tapes Inside Baseball Saturday Night from there.  

So yeah, that's a thought.  Or three.

The Fifth Wheel in San Leandro .It only serves breakfast, brunch and lunch. I am assuming you are staying at the Airport Hilton, right? It’s less than 10 minutes away.  This place is perfect if you are at the Airport Hilton then go to the game as it is on the way to the coliseum and only a few blocks away. It is a very popular local breakfast place usually full but you can still get a table in 5-10 minutes or so never longer really. From the airport Hilton you just drive down Doolittle towards San Leandro, make a left on Davis Street, drive down Davis Street towards the San Leandro BART station and make a left onto San Leandro blvd and it is one block up on your right. It is little hole in the wall place, which makes a great breakfast. After breakfast just continues on down San Leandro Blvd towards Oakland and bingo you are at the Coliseum in 3 minutes.

they're known for their homemade ice cream, but their breakfasts (and other meal food) are surprisingly good. They also offer discounts for Oakland A's fans who wear regalia on a game day. During last year's postseason Fenton's proundly flew the A's flag outside the restaurant.

Marty Lurie often broadcasts his shows from Fenton's, and loves meeting fans. His show also gets broadcast from Crogan's Montclair, which also has decent food.

has been a featured discussion on AN for the second year now.

on E12th st. near Lake Merritt, has great Mexican food (y Margaritas).   Best mexi food in Oakland IMO.   I can't think of anything better in the summer.

There are a number of Ethiopian restaurants in the Temescal neighborhood that's been mentioned here.  Asmara is at about 51st and Telegraph--I used to live over it.  It's good food and a great experience.  Red Sea is nearby and good, too.

At Tommy's Joynt in San Fran (Geary and Van Ness)

we'e going to need to narow your requirements down a bit - especially for dinner, since you're only here for a couple of days and the options range from Taco trucks to Chez Panisse (in the gourmet ghetto on Shattuck Avenue in Berkeley and the putative birthplace of California cuisine).

So what kind of food, ambience and price are you looking for ?

try yoshino's on hegenberger road down the street from the oakland airport! you MUST try the lion king roll - california roll (i think?) with a piece of salmon & some special sauce on top and baked. SO GOOD.

On Clay in Downtown Oakland, walking distance from BART. French Vietnamese food. Nice, but still casual, and won't break the bank. I've never had anything there I didn't like.

millbrae in n out a few yrs back, there's one now off hegenberger across 880. :) don't want to hear your wife expects more.
