Tip-Top is a cafe in New York City.
Ron Alexander and Jillian Holtzmann conducted a successful test of their Remote Access Teleportation Unit then left Jimmy's Apartment and went to Tip-Top for lunch. They ordered and sat at a table outside the cafe. Holtzmann noticed weird readings on the prime universe's P.K.E. Meter and her P.K.E. Meter that weren't ghost-related. Ron could care less but he soon was hailed on the walkie talkie by Jimmy and alerted him the teleportation unit was acting weird. Ron and Holtzmann bolted and teleported back to the apartment. The waiter returned to an empty table and swore.
