Mexican food is great, but every now and then I crave a nice hot, grilled, cheesy sandwich. The best place I have found in SA for this craving is Zito's Deli. Their "Serious Sandwich" is just fabulous! They have two locations that I know of: Broadway about a 1/4 mile north of 410 and at Blanco about 1/4 mile south of N1604. Everything else on their menu is great, too, but the Serious put them on the map!
If anyone knows of other good places let me know.
