Mill Valley Yellow Cab

There are three taxi service names in Marin County using an address of 777 Meadowsweet in Corte Madera. One name is Mill Valley Yellow Cab 380‑8009; another is Tiburon Yellow Cab 332‑1822; and, the third is Sausalito Yellow Cab 289‑1088. They must be the same company since they have the same address.
Last night I called the Mill Valley Yellow Cab number and made a reservation for an airport ride at 6:40 AM today. The time came and passed and no cab arrived. When I called the phone number there was no answer. This shows that you cannot rely on this company for an important ride.
After trying to find another taxi I was referred to Radio Cab at 485‑1234. The woman who answered said she would try to find me a cab, and one arrived a short time later. The driver was nice and fast. Radio Cab will be my first choice in the future.
