I just ate a perez and I have to say that I was impressed. I ordered the Wed special which was under 6 bucks and got the following:
Basket of Tortilla Chips
2 Salsas(one smokey and one salsa fresca)
Costillas de puero con calabasistas(pork rib tips with zucchini)
Rice and beans on the side
a stack of warmed corn tortillas(too many too possibly eat)
I assume there was no zucchini in the dish unless it was really mashed up but the rip tips were really good because of the spicy sauce they were strewed in. It also came with rice and beans. I ordered a coke with it also and the total was around $7.50 which is an incredible value and I left a few bucks for tip. It had a mexican cantina feel to it and I will definitely make the trip back. If anyone is in the area I would recommend giving it a try.
