Stopped in for a quick bite.
Ambiance: A clean and modern looking restaurant-bar with nothing really hispanic-themed. This place is meant to be a nice place out and not a hole-in-the-wall. The fact they have margarita slushie machines should set the tone for this place. Noise was actually not a problem despite them being at capacity and the staff were friendly enough.
Food: I got a few carne asada and pastor tacos which comes with access to the taco toppings bar in the back of the restaurant. The tacos were served in medium flour tortillas larger than the typical street-style tacos that use corn tortillas. They could have used a light toasting but instead were just served just-warmed so they quickly became soggy in the meat juices. I stayed clear of the toppings bar because it was stocked with cheddar cheese and anemic-looking tomatoes, corns, and black beans. Given it was winter, they probably were using canned or frozen vegetables. It would have been nice to see some more authentic ingredients like cotija or queso fresco. In the end, however, the meat itself was tender and savory although nothing was particularly outstanding.
Overall I'd recommend Puente Viejo for people looking for a nice date spot that happens to serve mexican food. The drinks people around me had looked good but the food itself is americanized and not for those looking for an authentic experience.
