I've been looking for a basic Mexican go to since moving to Phoenix and I think I finally found it.
It was a Sunday night so it was pretty dead. The decor was interesting for a Mexican restaurant - leather booths. There's a large bar inside and a decent number of TVs and a big Movie screen (playing Scarface while we were there). The staff was very friendly.
Everything was pretty cheap. We ordered the chips and salsa (costs extra, but the prices of the dishes make up for it). The house salsa is pretty good and has some heat. The chips are freshly fried.
They have Modelo on draft, which I've never seen before (but I'm from the Midwest). There's also a $3.00 draft special every night. Margaritas are also pretty reasonable, I think around $5.00 but I didn't try one. We got the chimichanga, pollo asada, and a jalapeno cheese tamale. Everything came out (disturbingly) fast as it does for most Mexican places. Again, everything was decent.
Can't really beat the price, atmosphere, and friendly staff.
