"Visited Hacienda last night with 6 work colleagues for dinner. We were a blend of North American based and France based people who were excited not to eat German food again. The restaurant was a good size, however lacked air conditioning or any fans, which made dinner a little uncomfortable.The food itself was good. I wouldn't say it was authentic Mexican but it was tasty. The guacamole was great and so were the chips. Overall the food was well priced and plentiful. We order lots of drinks and they were relatively good too.My only negative comment would be the service. We had a total of three people waiting in us. The younger server was visably annoyed with having to wait on Americans and snorted when one asked for ice. Also laughed at use when we said "danke", which I thought was not necessary. The woman waiter was not as rude but definitely not friendly either. The older man, who seemed to be the manager, was pleasant and I would have rather dealt with him the whole time."
