I've been here a couple of times. Once for take out (at their old location a block away) and the other time I actually sat down.
I'd definitely recommend sitting down to enjoy your meal if you plan on getting tacos because it just doesn't taste the same by the time you get home.
Overall the food is okay. Really I actually prefer Playa Cabana Cantina's (a few blocks over in the Junction) selection, food and price. I'm happy to see that they have been doing well but honestly, I don't find Mad Mexican anything extraordinary.
They lost points for flavour, menu selection and price, but kudos for atmosphere and location.
