First off, for those of you that like Dos Tacquitos, Gonza's was started by his brother. Now, my wife and I have visited it twice since it opened in December, so I'm going to cover each of the things that we had by category instead breaking down each visit. The first thing you'll notice on the menu is that it is only two pages and has mostly traditional mexican fare. I think that if you stick to this menu, you won't be disappointed. However, I recommend that you stray from this after 1-2 visits b/c there are some nice surprises to be had.
Drinks: The house margaritas are very good. You can taste the tequila, but aren't over-powered by b/c the lime juice cuts it so well. They are also reasonably priced so that you can have two of them during a meal and not break the bank. We also tried the Spicy Pepino (a house specialty rita) that has cucumber and serrano pepper in it. I wasn't sure if I'd like it (bartender recommended it), but I thought the combination of heat/spice from the pepper and "cool" from the cucumber make for a very good drink. They also have homemade sangria and a wide variety of tequilas, but we haven't gotten to those yet.
Appetizers: On our first visit we had the queso picoso. It has a blanco (white) cheese base instead of the Americanized cheddar and can stand up on it's own. Our only complaint about it was that the portion size was too small for our liking, but that may be because we ate it quickly b/c it was so good. We tried the chiles endiablados (bacon wrapped pickled jalepenos stuffed w/cream cheese) on the second trip and have found our new favorite appetizer there. Once again, there's a definite heat from the jalepeno, but the bacon and cheese add plenty of flavor/coolness to cut it. Loved it.
Main Course: I had the carnitas (pork) tacos with the tortilla soup as a side while my wife had the tinga (chicken) tacos with the beans as a side. For me ordering tortilla soup is always an adventure b/c restaurants all seem to have a different take on what tortilla soup is. At Gonza's, it's more like a stew (almost like a chili) and heavily laden with meat and beans which is right up my alley b/c I'm a huge chili fan. My wife lived in Costa Rica for a year and she said based upon her experience - the beans were clearly authentic central american fare and had been cooking all day. Each order of tacos has three small tacos in corn tortillas which seemed to us to be great portion size - you walk away full, but not stuffed. The spices on each do a good job of bringing out the flavor of the meat, but also come with sauces on the side (green chile sauce for the pork and red sauce for the chicken), so you can tweak them more to your liking. On our 2nd visit, my wife had the El Platano (plantain stuffed w/chopped fajita steak, rice, chipotle sauce) with the beans and raved about it. Once again, not something that we would have ordered normally, but it's the favorite of the owner and he talked us into it. Speaking of which, I'd definitely try to meet the owner when you visit. He let us know of a few things that you can get off the menu, but you have to ask.
We had a great experience both times, so give it a try. We're very glad we did.
