- CBCaleb BatesJun 20, 20261.0When you're only open 2 hours a day, opening 10 minutes late is pretty bad
- KSKayla ShinMay 26, 20261.0They definitely don’t open at 11am. Was waiting about 15mins since 10:55 and still no one showed up. Someone else waiting said they sometimes don’t open til 11:30am or noon.
