Is there a good hair saloon in the hotel or somewhere nearby?

Where is Dry Bar at North Park and do I need to make an appointment for blow dry and styling on 13th and 14th April?how pricy is the Dry Bar saloon and how do I get there from my hotel Hilton double Tree Dallas? How far between Hilton and Dry Bar saloon

There are good ones at north park mall! A bit pricey but it's so close to the hotel! They have a free shuttle, too!

Not sure how pricey or if you need appointment or not it you looking at about 5-8 mile trip
