Newspapers & Magazines -- Indian Express, Hindustan Times, and The Times of India are good national dailies that provide the lowdown on (largely) the political scene. Outlook and India Today are weekly news magazines that cover a range of issues; of the two, Outlook is more populist and interesting to read. Time Out New Delhi (Rs 50) is a superb source of (sometimes sycophantic) information about every conceivable activity in town, with good accounts of new establishments and entertainment events; you can access most of it on www.timeoutdelhi.net. It's considerably better than First City, a reasonable monthly magazine carrying comprehensive reviews and listings. Delhi Diary is a city guide published weekly, and The Delhi City Complete Guide and Magazine (Rs 20) is published every 2 weeks; both are available at hotels and tourism offices and include events listings. You can also check out the latter's website at www.thedelhicity.com. A good Web-based source of information on Delhi is www.gocityguides.com for general advice as well as what's on the cards for the month, but reviews are even less critical than Time Out. For travel further afield, Outlook Traveller (www.outlooktraveller.com) is a top-quality locally produced travel magazine.
Post Office -- Try the post office at Parliament Street (tel. 011/2336-4111) or the GPO at Gol Khana, 5 minutes from Connaught Place. But best to ask your hotel to mail items.
Restrooms -- Avoid free public restrooms but in emergencies, you can use the Pay & Use facilities (Rs 2) or independently managed Sulabh Shauchalya ("shauchalya" means toilets), which are slightly better maintained.
Safety -- Delhi, like the rest of India, is relatively safe, though the city has seen an increase in crime. It's unwise for women to travel alone at night.
Weather -- Delhi's summers are notoriously unbearable; October/November to February are the best times to go.
Yoga & Meditation -- Sivananda Yoga Sevashram (tel. 98/1132-8067; www.yogayogini.com), Studio Abhyas (tel. 011/2696-2757; http://abhyastrust.org), Sri Aurobindo Ashram (tel. 011/2652-4807), Tushita Meditation Centre (tel. 011/2651-3400; www.tushita.info) -- all offer short- and long-term classes.
