As mentioned, you'll be there during Flower & Garden, so there will be the additional booths all around (seems that some are pretty much permanent now). Aside from those, my general favorites year-round are:
Meatball pizza at Connections
Bechamel, ham, & cheese crepe at Creperie takeout window
Tacos de barbacoa at San Angel Cantina
Smoked port butt platter at Regal Eagle
For the F&G offerings, I like the Germany potato pancake with ham, onion & sour cream
Corn beef brisket hash at Sunshine griddle
And I love the Food & Wine festival's Brew-Wing at Odyssey, which has popped up a few times - wish it would be there for F&G - actually, wish they'd just add that as a year-round spot, put all the tables back in Odyssey, and just make it a full time beer & wings joint!
