Saw Juan Mon's on the travel channel as one of Houston's best sandwich shops and they were right! I had the Buenos Aires and it was great. Will definitely be back to try the others!
The sandwich selection is great. Handmade milanesa sandwich is one of their best. The bottled craft brew selection is small, but a perfect match. Ask for the hot sauce with your sammich.
Remember spaghetti on a sandwich after a late night bender in college? Yeah, neither do I, anymore. Jog your memory; try the Venice (spaghetti, salami, provolone, onions, & sour cream on a baguette).
