Havana South is an excellent upgrade over the skeezy Iguana Lounge that was once at the corner of Wharf and Union. This is a huge space, to say the least. The bar itself is plenty big enough to handle many people and the space is well laid out. There is a ton of outside seating as well.  For now this will be a great summer spot for drinks as long as you don't plan on hammering back a bunch.
