If you come to Louisville you...
If you come to Louisville you definitely must visit Churchill Downs, home of the Kentucky Derby. Besides watching the horses run (and hopefully winning some money!) you can visit the Kentucky Derby Museum. Louisville is steeped in history. It became a city in 1798, and is considered the 'Gateway to the West'. Louisville is nestled in the Ohio Valley on the banks of the Ohio River. The one thing I miss about Louisville when I'm away is it's lush, green countryside.
If you want to buy fireworks:...
If you want to buy fireworks: firecrackers, mortars, the cool little tank things, just head across the bridge to Indiana. There are plenty of stores there that sell them, and many have either huge signs, or billboards to show you where to go.
NY Pizza Pub!
Johnny V's is a pizza pub located in J-Town on Watterson Trail. It's a pub atmosphere with TV's for the sports minded. The pizza is very good. New York style. Brews on tap are very reasonably priced. The owner, Johnny V, is a great guy originally from NY but relocated to Lville. His hospitality alone is one reason to visit the joint. Also try their famous sub, the "spiedie". NY style pizza with any topping you want!
del Barrio Taqueria
You walk into this place and it's just a small, not-very-busy Mexican cafe. There are 3 or 4 tables to the right, and a TV with some news on, hanging from the ceiling. On two walls there are stands with Mexican candy and treats hanging from them. I think I was perhaps the only one here who was not a fluent speaker of Spanish, too! But the best part is the food here! I got an Asada Torta (seasoned steak), which is on like a kaiser roll-sized bread, with shredded steak, lettuce, tomatoes, onions, jalapeno peppers, some cheese, and avocado/bean paste if you want it. It was delicious!!! Very authentic to me. And they also have tacos, which are apparently served open-faced. Ah, I will have to try these! At any rate, note that this is NOT a fast food restaurant... you'll have to wait up to 10 minutes for your food to be finished cooking if you're taking out. It's worth it! I plan to return here again, definitely!!! so far, the Asada Torta
As someone that never understood the excitement of horse racing, I am now a believer! Even if you don't like gambling, it's fun to see the horses themselves. However, the race is much for fun if you do place a small wager ($2 is the smallest). Also, Churchill Downs is the site of the famed Kentucky Derby!
