I've never been to Mexico so cannot comment on the authenticity question, but as a new pre-theatre venue for me, it ticked all the right boxes. I have to agree with the SM reviewer as the room itself is somewhat uninspiring – personally I went for hotel foyer rather than dining room, but that doesn't detract from the enthusiasm and friendliness of the waiting staff who seemed genuinely pleased that the food was appreciated. The “top shelf” guacamole was interesting being that it is made at your table, but would have been better with slightly riper avocados and although advertised as sufficient for two, make sure your dining companion does not have a big appetite! Our mains or steak wrapped around a pepper and steak with bacon wrapped prawns were very good but the accompanying sides of rice and sauteed vegetables were a tad disappointing – vegetables being somewhat overdone and rice just lacking in any sort of flavour.
That said, it was an enjoyable meal (margaritas v good and half price at the time) and I will return but probably for a swift informal meal, rather that a leisurely, lengthy evening.
