When you've had Yogurtland, it's hard to find another yogurt place attractive. I'm afraid I have been ruined, but don't let that affect your experience at Menchies.
I like the whole self serve idea, just like Yogurtland, but it seems to miss the mark on quality and variety of toppings. The prices are about the same and the yogurt is just as yummy, but the toppings just don't have the same WOW factor. Not gross by any means, but there is some work to be done.
I would head to Menchies if it were close to me, but I'm afraid Yogurtland has won this round.
