Mexican near the I-95 corridor?
In addition to Los Sarapes, they have another outlet in Blue Bell called El Sarape that might be easier to get to. You can take the blue route north and get off at the Plymouth Meeting exit.
If you go that way as well, you could get off at Fort Washington and go to the upscale Cantina Feliz. This restaurant is quite good, and very similar to the Iron Chef Jose Garces Distrito in Philadelphia.
El Changarro in Bensalem is quite good. Street road exit off of 95.
In Southhampton just off of Street road Las Margaritas is decent tex mex food.
