I had a few tacos here, and it was ok, but by no means great. Other places have a variety of salsas, and don't charge extra for that. Costa Vida lets you pick one, and it wasn't even that good. Carne asada was basically flavorless, and the tacos fell apart.
Lots of people rave about the "sweet pork", and it was fine. It's pulled pork in a sweet BBQ sauce, I'm more a fan of grilled meat, which Costa Vida doesn't seem to do well. Still, it's not a 2-star place, I'd stop by again if I was there and had to grab something quick.
