BY BRADEN CARTWRIGHTDaily Post Staff WriterPalo Alto City Council wants more types of businesses — such as bars, cat cafes, medical spas and larger gyms — to have an easier path to opening. The city is working to relax its permitting rules in an attempt to fill vacancies around downtown and California Avenue. For bars, the city currently requires businesses selling alcohol to have at least half of their revenue come from food sales. But members of the Retail Committee said they’d be open to allowing pure bars and were surprised that such a ban existed. The city allows open containers at times on California Avenue, so it’s strange to not allow bars there, Lythcott-Haims said.
