Do NOT eat at M4 Burritos... unless you want to receive rude service, to have uncooked rice in your burrito, and to go thirsty because they offer cups of water to some but not all clients.
My friend and I each ordered burritos; after taking a bite, we noticed that some of the rice grains (not all) were completely uncooked. We brought it up to the workers. Rather than replace our burritos, she tasted a small sample from the bin and told us "it was fine." Any respectable establishment would try to make amends with their dissatisfied customers rather than tell them that they're wrong; that's customer service 101.
Not to mention, they "were out" of cups for water, which was weird because I saw another client get a cup of water 5 minutes after we ordered.
I will NOT be returning to M4 Burritos.
