Technically, yes. Mellow Mushroom has a late night happy hour that starts at 10:30pm till 2:00am, Sunday thru Thursday.
They do have happy hour from 3 to 7 on weekdays. I called them. Also from 3 to 5 they have specials on appetizers. You may want to call for the daily specials. On a side note, they make fantastic fresh pizza, made to order, and it's worth the visit. I hope you enjoy and find some good drink specials.
