Keeping in mind that Yogurty's is a chain, I really like this location because it's close to promenade mall/walmart/where I live, there's always ample parking, and it's very clean inside. There is a happy hour for froyo on Mondays to Thursdays from 3pm - 7pm where you pay $5 and you can fill up a regular-sized cup with "unlimited" yogurt and toppings. It's not technically unlimited because they recently put a cap on how tall your froyo can be.
This location is right across from a high school, so I can only assume it gets super busy between 3-5pm (I never go at that time). Whenever I've been, there's always lot's of room to sit inside. The layout is very easy to follow and you can ask for sample cups to try the different flavours. The only complaint I have is that there's only 1 employee working at a time, so if she is in the back or helping customers cash out, you'll have to wait until she's done to get a sample cup, refill a topping, etc.
