If anyone here is new to littleton, and is interested in going to a casual burger place, red robin is the place for you. they have a bar where you can always meet new people, or you can go with your family for dining in. their service is very very fast and excellent for big groups. they also have some of the best drinks. some of them even let you keep the sweet-looking beaker! i definetly recommend this place for people just looking for a place to have a fun time with friends!
