I decided to try out Rudys for breakfast and working. I love their tacos (Red Chile + Sissy Sause = BEST EVAR). Rudys has tons of space, if you're not around during main lunch and dinner crowds you can hang out in the outer area, there is great music playing (little older music so it's kinda fun). And its not distracting. The temp is comfy (well right now in mid October) too! (Inside may be more distracting and a little less awesome).
Pro's: Free Wifi, Great Breakfast Tacos (cheap too), Good music, and most of all not distracting.
Con's: Again you really should buy food, and don't go around busy times.
