I got the white queso, it didn't taste/look like Velveeta, thought it was good,
The queso I referred to was not white, so that's very good to know they changed it up.
Oh, I liked their salsa for the tortilla chips.
Same. The salsa and guac were my favorite parts (I am a guac fan though)
I also got that poboy.. or one very similar.. and that's where I got the bad impression for sure. Mexican food on poboy bread is already odd, but it wasn't done very well either. I had that same hard, flaky bread you're referring to.
My sandwich had a decent amount of meat, but it completely fell apart by first bite. The pieces of meat on the sandwich were not cut up, so taking a bite out of tough meat just makes the entire piece come out of the sandwich.
I got a call to go out to Lava Cantina last night because my friend was there to see a band. I hear the drinks are good, so if I'm ever in Perkins Rowe (which is never, but maybe someday), I'd be down to sit at their patio bar sans food and enjoy the day.
