I'd been to Modern Market in Denver before and was so excited to see one opening in Ahwatukee! I've been 5 times and every time has been great. The decor is light and casual - there is also plenty of outside seating but it's been to hot to try that yet.
There's always at least a small line when I'm there, but they get the food out quickly and correctly. I've tried pizza, salad, sandwiches and the meat / tofu and sides platter - I have truly liked everything so far. It's probably the best healthy fast-casual restaurant we have.
