Ditto on Don Emiliano! Lovely courtyard and and interesting menue, with much more reasonable prices than some of the nearby high-end places. Started with a plate of mini blue crab tostadas, followed by a very fresh sea bass in simple sour orange sauce. Superb margaritas.
For breakfast, everyone recommends the French Riviera. A very nice atmosphere and good coffee and croissants, but the huevos dishes had very bland sauces.
