First of all, The Climbing Wall ha very helpful and knowledgeable staff who are eager to teach newcomers like myself. Some rock gyms I have been to are very elitist in that you feel like you're the one left out of some inner club, not this place. They are all about getting you interested and involved with climbing and the climbing community.
The walls them self are great with the perfect range of easy to challenging walls. They also change routes frequent enough to never get bored.
Pricing is also very good (especially if you are a student).
