Cuban food is awesome. I didn't know you stayed in the Portland area so if you are ever up in Seattle and want some great Cuban/Caribbean food hit up this place.

If you want a sandwich get either their Midnight Cuban Press (my favorite) or Hamon & Queso Melt. I've had most their sandwichs (minus seafood because I don't like it) and they are all great but those two are the best in my opinion.
Also the 1/2 Chicken Dinner and the Cuban Roast Plato are very good too.
