Honestly, I have had only one marginal experience, and it had to do with a waiter and not the food. It ia always hot and tasty, and the service is generally up to the task. Try again all who have had a bad experience.
Like most Americanized Mexican restaurants, the food at Hacienda looks authentic and flavorful, but is pretty bland and tasteless. The drinks are crazy overpriced, the kind of prices you would pay at a strip club.
The only reason I still continue to visit Hacienda is everyone else seems to love it.
