Great on a hot Phoenix day. Custard is like a marshmallow cloud and slushies are delicious. Mixing the two together is the best.
The Windows and glass door where so dirty and covered in kid's finger and hand prints it was a turn off. The smell inside was also not pleasant like rotten milk. But I enjoyed my dessert on a 105 degree day. A little more care to clean the interior and I would give 4-5 stars.
