You're better off taking public transportation or taxis on weekend nights, unless you're heading downtown (Financial District or Union Square) and are willing to park in a lot. There's only street parking in North Beach, the Mission, Castro, and the Haight, and finding a spot can be practically impossible. Muni stops running between 1 am and 5 am but has its limited Owl Service on a few lines—including the K, N, L, 90, 91, 14, 24, 38, and 22—every 30 minutes. Service cuts have put a dent in frequency; check www.sfmuni.com for current details. You can sometimes hail a taxi on the street in well-trodden nightlife locations like North Beach or the Mission, but you can also call for one (415/626–2345 Yellow Cab, 415/648–3181 Arrow). The best option by far is booking a taxi with a smartphone-based app (www.uber.com, www.lyft.com). Cabs in San Francisco are more expensive than in other areas of the United States; expect to pay at least $15 to get anywhere within the city. Keep in mind that BART service across the bay stops shortly after midnight.
