Went here for the first time on Friday night, and was skeptical of all of the hype.
We ended up having GREAT experience here.. mostly due to wonderful, friendly, well trained and professional service, especially for such a relaxed and laid back atmosphere.
The food is also excellent... everything was deep fried and mayo and sour cream laden.. but fried and spiced perfectly and not greasy or overwhelming. We had almost every taco and the spicy squid appetizer (my favorite!). My friend and I agreed that the el Pastor tacos were the best.. but all were very tasty.
The atmosphere is great.. very casual and backyard- picnic combined with a drive in movie (the menu!) kind of feel, definitely not upscale, but unique and comfortable.
You most likely WILL have to sit at a communal table with complete strangers, which was ok & fun for us, but might not be for some.
Anyway, the highlight of the place for me was the kindness of the waitstaff (in a city where most trendy places tend to come with attitude laden restaurant staffs).
