Yes - I realize that these are two completely different types of restaurants! ;o) We are planning a pre-wedding dinner and are trying to narrow it down. I really wanted the Mexican feel and mariachi band Hacienda Sisal offers, however I haven't eaten there.
I really enjoyed Puerto Madero and the outdoor seating, though it is more expensive. Anyway... Any thoughts/opinions would be much-appreciated. I'm so glad that I can ask about these types of things here. I'm quite indecisive, yet I've found this board very helpful! :o)
