My two favorite places for dinner with walking distance of MAC:
Nunthaporn for very good Thai. I'm particularly fond of the Jungle Curry there.
Mango's for casual, order-at-the-counter Mexican.
Blue Adobe, as mentioned above, is also good, but a bit more of a walk to MAC -- a little over half a mile.
There's an odd themed bar/restaurant called Monsterland that's actually better than one would expect it to be (and they have a decent local beer selection). Mangos is a decent fast Mexican spot. There's also a Thai restaurant called Nunthaporn's that's less than a block from the MAC...it gets good reviews though my one visit there was "meh".
Those are all within walking distance of the MAC. I do agree that in the general area, Blue Adobe Grill is probably the best bet.
