We have been to Sirena Taco twice. The first time we went we loved it and couldn't wait to go back. The only negative for that trip was the prices. The tacos were delicious but for the price should come with at least one side.
Also, to have to pay extra for Chips and Salsa is discouraging, I've been to many Mexican restaurants and I can't think of another that doesn't include chips with your meal!
On our second visit, it was Saturday night and the place was hopping! We got seated at a table near the bar which wouldn't have been a problem except the table was so small that when our food came we had to move the plates diagonally to get them to fit and then juggle to get our drinks up without spilling them since it was so crowded.
As far as the food went it was good but as mentioned earlier the prices are high. The guacamole was delicious! I ordered a tequila infused pineapple Margarita which really just tasted like a bland slushy so that was disappointing.
We'll probably give it another try, but I doupt it will go in our regular rotation. Too bad cause I really hope they can be successful.
