Ive eaten at most of those places, Romeos :bad , La Mesa was just okay, La Fondas :bad , Julios used to be decent, but the last few times I was there, it sucked. Roja was okay, good atmosphere. I didnt really care for the place out across from Sapp Brothers.
I heard that California Taco was pretty good, and my coworkers used to get Alvarados quite a bit (there is one on 90th north of Maple and in CB) and they seemed to like it. I used to date a gal that was half Mexican, so we ate at El Alamo and it was pretty good, and Netties, also pretty good. Hectors is pretty decent, they have the best Margaritas in town, IMO. Ive heard that that big restraunt and bar down on 33rd between L and Q is pretty good, but Ive never eaten there. Mattias has good 1.29 tacos after 9pm on weekdays, but their cheap Margaritas will do bad things to your intestinal tract, if you get my drift :thumbs but we used to have a great time there when I was in my early 20's and their tacos were a buck, and a pitcher was $4 :wasted
The place I like the best looks like an old Taco Bell, its on 33rd and Q, called Taco Durango. I love the place, the enchiladas and fajitas are awesome!!
