i am not sure there is still an a la carte menu (likely), but you're already better off just booking from their inexpensive buffet meal (p595 on evenings, if i remember correctly).
there will be several kinds of salad (pako, ensaladang talong, salted egg and tomato, romaine), soup, and five main dishes, which were caldereta, roast chicken, and a lengua, among others. good deal!
more than that, this is located right across san agustin church in the plaza san luis complex, which is a reconstruction of oldintramuroshomes during the spanish period. spanish decor, beautiful wooden furniture (like the curved and straight-backed mariposa chairs), and rugs cover the floors of this mansion repro. and at 7:45, there is a skilled rondalla band that performs an impressive range of cultural dances. we were entertained for over an hour, and the live music helps this performance stand out above the rest, since you get one, or the other, and rarely both.
we played dress up for this, had filipino fun, and had a grand evening.
the food is a 3.5 to me, but the show was tops, and worth repeating.
bring your parents and older relatives, your balikbayan friends, or for a themed evening, this is fun to go to.
it's best to park near the church, and tip the watch-your-car boys nicely.
