If you can only do one thing in OKC, you must go to the downtown area known as Bricktown. It's the only part of the city that's good for walking. There are so many attractions located downtown that everyone and anyone would find something they love here.The Civic Center shows theater, musicals, opera, etc. The Myriad Gardens (a top pick of mine)is a giant greenhouse with lots of exotic flowers and plants. Admission is about $5. The Cox Convention Center is also located in this area. You could catch an OKC Blazers Hockey game, Hornets Basketball Game, Concerts, and shows. Built very recently, it's a clean and new facility that will not disappoint.Restaurants in this area include Spaghetti Warehouse, Chellino's (Mexican), Zio's (Italian), and the new restaurant and bar "Toby Keith's I Love This Bar". Although I have not yet tried the latter, my pick for downtown restaurants would be Chellino's, a family owned restaurant that serves great Mexican/Tex-Mex food, including homemade tortillas and the best chile rellenos around.Also located downtown is the OKC Museum of Art. It is very good and one of my top picks for a downtown attraction. The most impressive collection there is works by Dale Chihuly. There are over 1500 pieces of blown glass by the famous artist including a breath-taking 55 foot tower and 9 foot chandelier.A popular attraction is a ride on a river boat around downtown OKC, and is very relaxing on a cool night.Lastly, my number one pick for OKC is the National Bombing Memorial, located a few blocks northeast of the above-mentioned area. It is a moving memoriam to those who lost their lives in the bombing of the Murrah Federal Building in 1995.
