Not a lot of people know about the Yellow Deli but you have to check it out! The place is open 24 hours! When you walk in to this place you will LOVE their decor. It's so homey and comfortable, a great place for tourists to get a feel of Boulder and for locals to have a nice quiet simple place to hang out. Their yogurt parfait, which is normally a really simple food is AMAZING! You can tell they take a lot of time in every meal they prepare because it's all so unique and tastey. GO!
