Like the look and possibilities for this place, but if part of the premise is having street tacos for late night (after 10:00) dining, you should be able to deliver. I was told at 10:15, they didn't understand the POS and so I'd have to wait 20 minutes to order. Don't make your problem my problem if you want to be successful.
It just got worse as the night progressed. We told our waiter and someone at the hostess desk on our way out about the problems with the outdoor taco bar. Rather than offering to help, they just focused on how busy they were. Fortunately, Dick's Hideaway a short drive away was much more accommodating and they even had a late night happy hour! They were busy, but found time to deliver great food and customer service.
