Southbound was fantastic! We had a wonderful experience - food, service, atmosphere - so I really don't understand all the bad reviews they are receiving...
I thought they were surprisingly cheap when compared to other locations. I got out of there with 2 tacos, chips and pico (shared at with table), margarita and the street corn appetizer for $17 (and that was including tip). The tacos were $3.50 each and most places are charging at least $5/taco.
They had a salsa bar (the chipotle crema, harvest salsa and the verde were delicious) and I was a little disappointed that we had to purchase chips and pico to be able to enjoy the salsa bar as is but at the end of the day, that really wasn't that big of a deal. People are also stating that the menu is small but I get overwhelmed with large menus so it made it easier for me to decide and it allows them to put quality in.
The place itself was just very warm and welcoming - the large open room, the windows, open garage doors, and large COVERED patio seating. We walked in and immediately just felt a sense of relaxation.
