We went to Cantina Conchita on Saturday with some friends. We waited 15 minutes for our drinks and then for each additional drink we ordered we had to wait around 10-15 minutes. It was a little over an hour until we were served our food. We had ordered the Tuna Dip and Guacamole as starters. The tuna dip was excellent but the guacamole was like whipped sour cream that was green like an avocado. Definitely not guacamole. So I wouldn't recommend getting this. I got the 200 gram Argentinian filet and it was very delicious and tender. My husband got the fajitas and they were also quite delicious. In all the food was good but make sure you have a significant amount if time to eat here since the service is so slow.
